How much does a cube of sand weigh. Concrete m200 - specific gravity of the material How much does 1 m3 of concrete m200 weigh
Concrete is an integral part of renovation or construction. It has high strength, is easy to use and provides buildings with durability and reliability. One of the main technical characteristics is the mass of concrete in one cube. Its value makes it possible to evaluate the composition, physical and mechanical properties of the material. This value is not constant, because, depending on the specifics of the work, concrete is divided into several types, which differ in the ratio of components, structure, and most importantly, in specific gravity. Before starting construction, it is necessary to make a careful calculation of materials, and the question often arises, how many kilograms of concrete are there in a cube?
Separation by Specific Gravity
- Particularly light - up to 500 kg per 1 m3. They contain air cells with a diameter of 1 to 1.5 mm and many pores (they make up 85% of the total volume). The cell size is up to 1.5 mm. The solution is prepared from cement, sand and without the use of large fillers. These include foam concrete, aerated concrete, which provide high thermal insulation, for example, when sealing seams and joints.
- Light - 500-1800 kilograms per cubic meter They also have a porous structure due to the presence of lightweight fractions: expanded clay, tuff, pumice, vermiculite. Contains 600 kg of sand per 1m3. From such a concrete mix, blocks are made that make up the partition walls, lightweight structures.
- Heavy - 1.8-2.5 tons per cubic meter. They can contain large rocks as a filler - gravel and crushed stone, as well as coarse sand. In addition, the mass of the material includes up to 200 liters of water, cement (250-450 kg). This variety is the most popular, has a wide range of applications: from load-bearing structures to concrete foundations.
- Particularly heavy - 2.5-3.5 tons per 1 cubic meter. Filler - barite, hematite, magnesite. Given the huge mass, it is rarely used, mainly for special industrial facilities that require a high degree of protection.
Separation by brand
They are called classic because of the wide scope of application. They have several brands that differ in the proportions of the components. The most common are listed below:
- Mark M100 - specific gravity 1 m3 = 2494 kg. Main application: preparatory, construction pavement, installation of curbs.
- Mark M300 - belongs to the class heavy concrete. Weight varies from 2.2-2.5 tons per 1 m3. M300 is used for the manufacture of monolithic foundations, fences, walls, flights of stairs, floor slabs.
When working with any kind of building material, it is imperative to know its main characteristics in order to facilitate its use. The properties and characteristics of concrete should be known first of all, because it is one of the most popular materials.
The weight of the product significantly affects the installation and installation process, and also affects how much the entire structure will weigh, its volumetric characteristics. From this, it can be said that lightweight material much easier to work. And everything is greatly simplified if you know that this indicator can be controlled and achieve the desired weight. But within what limits can you work? How much should the concrete we need weigh, how to regulate its weight so as not to affect the insulating qualities?
First of all, we need to calculate the weight in order to understand at the design stage how many kg the base will have to withstand. Let's find out together how much concrete should weigh and how to understand it.
Classification of the specific gravity of 1 cube of concrete:
The most common way to classify the weight of a cube of composition is by division according to specific gravity. According to the volumetric mass, there are such types of concrete as:
- Particularly light: maximum weight of 500 kg per cube. The content of air cells with a diameter of 1-1.5 mm and a porous base is characterized. These are foam and gas blocks familiar to us, which basically have not only classic cement and sand, but also a foaming agent that creates cells with air. This allows you to create a low weight and good thermal insulation ability.
- Light: 500 kg - 1.8 tons per cubic meter a porous structure, which is determined by how many different light fractions it contains, such as expanded clay, tuff, pumice or vermiculite. The sand content in them is about 600 kg per cubic meter. It makes excellent blocks and partitions, lightweight structures, lightweight blocks, like cinder concrete.
- Heavy: 1800 - 2500 kg. Often they contain gravel and crushed stone, sand of large fractions as a filler, mineral fillers, quartz sand are used. There are also about 200 liters of water and 250-450 kg of cement. This is the most commonly used concrete in our construction.
- Especially heavy: 2.5 -3.5 tons. Fillers based on a group of minerals such as barites, magnetites, limonites are applicable here. Considering the huge mass of such mixtures. In principle, you should not even get hung up on them, because. they are in private construction and are not closely used, mainly in industry.
Determination of the weight of 1 cube of concrete
How to determine how much is the weight of concrete? To do this, to begin with, let's look at SNiP No. II-3, where for our convenience they made tables for calculating the weight of different products, depending on the type of filler. Naturally, we attach the table below for you:
Please note that even in this case, everything is approximate, but you can already use them if you need parameters when filling. You will not find complete and accurate data, up to one kilogram, anywhere. And why? But because how much 1 cube of concrete will weigh depends on many factors.
In practice, note that:
- The mass of the solution of the solidified mixture will differ from the mass of the dry components with water when kneading;
- The density of the composition is determined for the most part filler and its structure;
- Specific gravity and density are different concepts both in meaning and in name;
- The method of preparation is the main factor affecting the mass of the cube;
- The density of concrete and the weight of 1 m3 will be much greater if you use the deep method of compacting the mixture. Its use will allow to achieve greater strength.
Do not forget that the main thing for us is to achieve the strength of concrete, which means to mix the solution in such a way as to get a certain brand. Often the weight of concrete depends on the grade you choose.
Pay attention to the characteristics of each of them. The most common in use is the M300 and M350 (v25). Which are used in private construction for arranging foundations, walls and partitions, flights of stairs and even ceilings, columns, etc. Both the M100 and M200 brands are widely used. Today, according to the data, you can find out how much a cubic meter of each practical brand weighs. The relevant table is attached:
According to most tables, the approximate weight of concrete used in private construction is 2300 ... 2500 kg per cube, which means that its average density is taken as 2400 kg / m3.
note
When calculating the weight of a structure, it is important to know the following data in order to avoid errors:
- It is impossible to allow the required mass of concrete to be obtained by calculating the specific gravity of each element of the mortar and adding these values together. This is the most common mistake that is often made. The fact is that these data will be extremely far from the real ones, because in fact a lot depends on the batch. One cubic meter of concrete will weigh differently with the same number of components. You can knead the mixture by hand or do it in a concrete mixer - the result will be different.
- Many people think that the higher the weight, the greater the strength of the material. The specific gravity does not affect the reliability and strength of the material. Only the density of cement in the solution can influence the brand, and the brand already determines the quality. Strength will also depend on the quality of the concrete mix and adherence to the instructions for its manufacture.
- The mass of the mixture that you have made will weigh differently than the solidified structural element, as a result of the evaporation of moisture.
- When kneading, even the most accurate calculation can be ruined by water. Be careful not to spoil the end result.
In this article, we tried to answer all your questions regarding the topic. Also pay attention to the video at the end, in which you will learn how to calculate the cubature:

Weight table 1 cubic meter of concrete
The range of application of cement mortar is very large: from finishing the walls of a residential building to building massive dams. Knowing the weight of concrete structures and reinforced concrete products is of no small importance in the design of various objects. To do this, you need to know how much one cube of concrete weighs, and what affects this value.
What does weight depend on?
When the question arises about the weight of a cubic meter of concrete mix, it should be understood that we are talking about density. She is one of the main technical parameters cement mortar. The unit of measurement is kg/cm3. The higher the density, the greater the weight of the concrete. Both of these values directly depend on the type of filler. It is according to him that the classification of solutions is made. We recommend that you study what characteristics are affected by the value of the specific gravity of 1 m3 of concrete.
How much does different concrete weigh?
Specifications It is customary to display by dividing into classes and brands. When solving specific problems, this helps to correctly and accurately select the concrete mixture.
1. Classes of concrete.
This is the most common (classic) type mortars. It is best suited for the construction of the main elements of load-bearing structures, pouring screeds, erecting fences, etc. The composition of heavy concrete includes large-sized and massive fillers: coarse sand, gravel, crushed stone. It is they who occupy the bulk of the mixture. A cubic meter of such material weighs 1800-2500 kg.
The name of the concrete group is determined by the structural features of the fillers. In the manufacture of expanded clay, vermiculite, perlite, various industrial waste. The porous structure of these materials reduces the weight of the cube of the finished solution to 500-1800 kg.
Sand is not found in all lightweight concrete. Where it is provided for by the recipe, its mass in 1 m3 is 600 kg. Lightweight concretes are used in the construction of building blocks, enclosing structures or pouring screeds.
- Particularly heavy (super heavy).
In production, metal fillers are used, which give the finished product a massiveness. The weight of a cube of concrete is 2500-3000 kg. In the composition of super-heavy mixtures, cement of increased strength is necessarily present. In private housing construction they do not apply. They are usually used to make protective structures. special purpose, for example, for nuclear reactors.
- Extra light (heat-insulating)
This group includes cellular concrete, in which there are no large fillers. In their composition, in addition to cement and sand, foaming agents are present. During the production process, voids are formed inside, occupying up to 85% of the total volume. Therefore, the mass of the cube is very low - less than 500 kg. To enhance strength, special plasticizers are added to cellular solutions.
Particularly light types of concrete are used in the production of blocks and slabs with high heat-insulating properties. Their disadvantage is weak frost resistance. Therefore, building elements with a porous structure require mandatory waterproofing.
2. Grades of concrete.
In the group of heavy solutions, there is an internal classification. It is determined by the different ratio of components in the recipes. Depending on this, the mass of a cubic meter of each brand is somewhat different.
Ratio table:
| Concrete grade | Weight of components, kg | |||
| Cement M300 | Sand | rubble | Water | |
| M100 | 214 | 870 | 1440 | 100 |
| M200 | 350 | 795 | 1080 | 175 |
Reducing the volume of the filler leads to a decrease in the mass of the cube and an increase in the strength of concrete. Replacing cement of one brand with another affects the strength. To prevent this, you need to make changes to the layout of the components. At the plant, such tasks are solved in laboratories. At home, you have to adjust the ratio "by eye", which can adversely affect the quality of concrete. Therefore, in the manufacture of cement mortars with their own hands, construction experts recommend taking the classic recipes of the components as a basis.
Weight table different brands concrete:
Based on the above data, you can easily determine the average weight of one cubic meter. Experimental studies confirm theoretical calculations and show that 1 m3 of concrete solution weighs 2400 kg.
The average cost of a cube of concrete
When the filling process large structures occurs continuously, it is advisable to order and bring ready-made concrete from the factory. Of course, it will cost more than manual kneading. After all, the customer has to pay for all production work, delivery, loading and unloading of the machine.
The final price of a cube of ready-mixed concrete is a variable value and depends on many factors:
- Brand - determined technical requirements for every type of building.
- Filler - a cubic meter of gravel-based solution costs 100-150 rubles cheaper than granite concrete.
- Remoteness of the working site - delivery by big city or in off-road conditions is more expensive.
- Boom Length - A concrete pump truck is not required in all cases.
- Days of the week - on weekends and holidays, the cost of a cubic meter of concrete mix is usually higher.
- Volume of the order – more favorable terms of sale are offered for wholesale customers.
Price table for ready-mixed concrete:
When only a few cubes of mortar are needed, it can be prepared on site. It is advantageous to use manual mixing when pouring small elements: stairs, garden paths, architectural details of small forms. The price of such concrete is quite affordable for any developer.

How much does 1 cube of concrete of various grades weigh?
Let's talk about what you need to know this characteristic. The fact is that the area of its application, strength, thermal conductivity and cost directly depend on the specific gravity (density) of one or another type of this building material.
The following “equality” is true here: the higher the density, measured in kg / m3, the greater the weight of the final product. By by and large, the weight of the solution depends on the type and mass of the filler: crushed stone, gravel, sand, expanded clay, slag and other types of filler. Accordingly, there are the following main types (types) of concrete:
- Heavy. The mass of 1 m3 is in the range from 1800 to 2400 kg;
- Lungs. Weight range 1 m3 from 500 to 1,800 kg;
- Particularly heavy. Weight range 1 m3 from 2450 to 2950 kg;
- Particularly light. The weight of the material with a volume of 1 m3 is up to 550 kg.
How much does 1 cube of concrete of different types weigh?
- heavy concretes. The composition of this type of building material includes large fractional fillers, characterized by a significant mass: crushed granite, gravel, river sand. In particular, the standard recipe for the preparation of 1 m3 of heavy concrete for wide use includes the following components: 1250-1300 kg of crushed stone (gravel), 650-700 kg of sand, 160-200 liters of water and 250-450 kg of Portland cement brand M400-M500. Scope of heavy concrete: any load-bearing elements, coupler, protections, etc.;
- Lightweight concrete. According to the name, porous (light) fillers are used to mix this type of material: expanded clay, vermiculite, foam perlite and waste from metallurgical and energy production. Lightweight concretes have a high porosity of the “body”, therefore they are used for the construction of: floor screed, walls of residential buildings, block products and internal partitions;
- Particularly heavy concrete. This type of material, as a rule, is not used in low-rise construction. Almost the entire volume of such concrete consists of large heavy components. High grade cements are used as a binder. Scope: construction of bridges, flyovers, protective structures of nuclear power plants and structures for hydraulic engineering purposes;
- Particularly lightweight concrete. These are the so-called "cellular" materials, which do not contain large aggregates. Lightweight concrete is a structural mortar made from cement, sand and a foaming agent. In this case, in the body of the solution, air pores occupying up to 85% of the volume. Particularly lightweight concretes are used for the production of "warm" blocks, slabs and non-load-bearing partitions.
Weight of 1 meter of cubic concrete of different grades
In accordance with GOST, heavy concretes are divided into grades from M100 to M600 (M100, M150, M200, M250, etc.). The composition of concrete of a particular brand depends on the ratio of the quantity: binder, sand, crushed stone, water, as well as on the brand of cement (usually Portland cement M400 or M500).
Accordingly, the mass of grades of 1 m3 of concrete of this type differs, however, so slightly that this difference can be neglected. In the general case, both professional builders and private developers use the figure 2,400 kg in calculations that involve the mass of 1 m3 of heavy concrete (no matter what brand).

How much should a cube of concrete weigh, calculated values and averages, formulas and calculation examples
The weight of concrete is a value that is very important both in the construction and dismantling of concrete buildings. The design features of the foundation and floors of the house will depend on it. The same indicator is used to determine the number and carrying capacity of the transport required to remove the debris when the building is destroyed. How to determine how much a cube of concrete weighs?
No one can give a definitive answer to this question without first asking a few clarifying questions. The weight of concrete is a value that depends on a combination of indicators such as:
- brand of cement;
- type of fillers;
- the amount of water used for mixing.
Depending on the above factors, the following types of concrete are distinguished, differing from each other in their specific gravity, that is, the mass of a cubic meter:
Extra light
Most often these are cement mortars filled with small air bubbles or pieces of perlite, vermiculite and other light minerals. They are used as heat insulators, when sealing various seams, joints, to eliminate cracks. They are unsuitable for the manufacture of load-bearing structures. In this case, the weight of a cube of concrete does not exceed 500 kg.
Lungs with brand M 100 or 150
The fillers in them are porous materials, for example, tuff, expanded clay or shell rock. There are types of mortars that do not contain either heavy or light stones in their composition. Their low weight is due to the presence of pores in the cement mortar. These include foam and aerated concrete.
A cubic meter of such mixtures can have a mass of 500 to 1800 kilograms. A significant proportion of them is occupied by sand, which in the cube of the finished solution can be up to 600 kg. Such concrete mixtures are used for the manufacture of wall blocks.
Heavy, grades M 200, 250, 300
These are classic concretes, in which gravel or crushed stone act as aggregates. They are prepared using a ratio of 1:2:4:0.5 or 1:3:5:0.5, where the first digit is the volume content of the binder component - cement, and the rest are sand, crushed stone and water, respectively.
For example, to prepare a cubic meter of such a concrete solution, it will be necessary to spend from 250 to 400 kg of cement, depending on its brand, 600 - 700 kg of sand, 1200 - 1300 kg of gravel or crushed stone and pour this mixture with 170 - 200 liters of water.
These values are inaccurate and can vary widely. However, concrete is produced in large volumes, so a few kilograms lost and added in the calculations will not play a significant role.
A cube of such concrete has a mass of 1800 to 2500 kg. The range of areas of its application is very wide. This includes pouring foundations and building monolithic walls, and the manufacture of reinforced concrete slabs and blocks. Such a solution is suitable for pouring screeds, paths, platforms, making fences and stairs. Concrete of the specified brands - the most demanded.
Particularly heavy, grades M400 or 500
Here, waste from the metallurgical industry (metal scrap), as well as magnetite, barite, hematite, are used as fillers. In the construction of residential buildings, such concretes are not used. The main areas of their application are the creation of protective structures on nuclear power plants, in bunkers for the storage of radioactive waste and other similar structures.
The weight of a cubic meter of such concrete is from 2500 to 3000 kg, most of which falls on large aggregates.
How to calculate the mass of a cubic meter of concrete
All of the above parameters are regulated by the standards of SNiP No. II-3, established back in 1979. AT this document more accurate values are given for concretes using specific aggregates (all values are in kg/m3):
- reinforced concrete structures - 2500;
- crushed stone, gravel - 2400;
- tuff - from 1200 to 1600;
- pumice and other fractions of volcanic origin - from 800 to 1600;
- expanded clay - from 500 to 1800;
- foam and aerated concrete - from 300 to 1000.
It is possible to determine the mass of a cubic meter of finished concrete based on its brand. The values of the specific gravity of concrete in kg / cubic meter are given below:
Table "Specific gravity of concrete (1m3) of various grades"
If you need data specifically for your concrete, and not average indicators, you can make the calculations yourself. To do this, you need to know the content and brand of each component of the mixture.
Let's give an example
It is necessary to prepare a cube of concrete grade M200 from cement M400 with the following indicators:
- crushed stone fraction - 4 cm;
- water-cement ratio - 0.57;
- sand density - 2.63 g/cm3;
- cement density - 3.1 g/cm3;
- crushed stone density - 3.6 kg / l
Cement for the preparation of a portion of such concrete will require 325 kg. This parameter is calculated using the tables given in SNiP by dividing the volume of water required to prepare a solution of the desired brand by the water-cement ratio.
Next, we calculate the total volume of sand and gravel. To do this, subtract the sum of the volumes of cement and water from the total volume (1 cubic meter or 1000 liters). The volume of water is indicated in the table - 185 liters, the volume of cement is obtained from the school formula by dividing its mass by density. Total we get 1000 - (185 + 325 / 3.1) = 710 liters.
Knowing the percentage of sand and gravel in the mixture (also presented in the tables), we calculate the volume of each of these components separately. It is not difficult to determine the volume of a part of the whole: multiply the total volume by the percentage of the component and divide the resulting value by one hundred. In total, with a percentage of sand to crushed stone in our mixture equal to 41:59, we get: 710 × 0.41 / 100 \u003d 290 liters of sand and, accordingly, 420 liters of crushed stone.
Knowing the volume and density of the components, multiplying them by each other, we get the weight of sand in kilograms 763, crushed stone - 1092 kg. If we add the mass of cement (325 kg) and water (185 kg), we get the mass of a cubic meter of concrete - 2362 kg / cubic meter. As you can see, the value is close to the tabular one (2430 kg / cubic meter).
There is an even more simplified way of calculating. To obtain concrete grade M200, the strength of which is quite sufficient to withstand the load of a private house, the volume ratio of cement, sand and crushed stone should be 1:3:5. If we add up all these parts (1 + 3 + 5), we get a total of 9 volumetric parts.
Knowing that one cubic meter is 1000 liters, we get one volumetric part equal to 1000/9 \u003d 111 liters or 0.111 cubic meters. Then the mass of cement in the mixture will be 0.111 cubic meters x3100 kg / cubic meter = 344 kg. The masses of the remaining components can be calculated in the same way as the mass of cement, or use the first method. The water-cement ratio in this case can be taken equal to 0.5. The values will be close, but not the same.
For private construction, as already mentioned above, this method of calculation is quite acceptable. In other cases, use the values \u200b\u200bgiven in SNiP. If you are unsure that you can make all the calculations yourself, then it would be wiser to use ready-mixed concrete purchased at the reinforced concrete factory.
Starting the construction of a house, or making repairs, sometimes you have to deal with questions that seem to be simple at first glance, but you can’t give an answer to them right away. It seems awkward to address such a question to specialists, but you need to know for sure. For those who can access the Internet, it’s easier - I typed in the search engine “How much does a cube of wood weigh” and in half a minute I got an exhaustive result. And by the way, really, how much?
Influence of humidity on wood weight
The weight of wood does not always have the same indicator. What does it depend on? First of all, from the moisture of the tree. If we compare, for example, oak and birch, it turns out that a cubic meter of oak weighs 700 kg, and birch weighs 600 kg. But it may be otherwise. Weighing a cubic meter of birch, we get 900 kg, and oak will show the same 700. Or in both cases it will be 700 kg. Why are there such different numbers? In this case, the moisture content of the wood plays a role.
There are four degrees of humidity: dry (10-18%), air-dry (19-23%), damp (24-45%) and wet (above 45%). Thus, it turns out that different rocks at the same moisture content have different weights, as in the first example above. If the humidity is not the same, then the weight can fluctuate in one direction or another. The standard humidity is 12%.
Different density - different weight
Another factor that affects the weight of wood is its density. The highest density of iron and ebony is from 1100 to 1330 kg / m 3. Boxwood and bog oak are close to them - 950-1100. In ordinary oak, beech, acacia, pear, hornbeam, the density is about 700 kg / m 3. It is even lower in pine, alder, bamboo - 500 kg / m 3. And the lowest is at the cork tree, only 140 kg / m 3.
Why do you need to know the weight of a cubic meter of wood
Having knowledge in this area is sometimes very important. By purchasing construction material, its amount is impossible for a non-specialist to determine by eye. Knowing the dimensions of the timber or lining, the material from which they are made and its moisture content, simple calculations allow us to determine the weight of the purchased goods. How much does a cube of wood weigh - in this case, the answer to this question will help you figure out whether the seller released the goods to you correctly.
Heat dissipation of wood
In addition, there is another indicator - heat transfer. She will come to the aid of those who use wood as firewood for heating. The higher the hardness, i.e. the density of the wood species, the higher its calorific value. Of course, no one will heat the room with boxwood, but choosing between linden and pine or birch and acacia, you can get much more heat if you know which of these species are the hardest. Information about the density of each tree can be gleaned from the tables, since all this information is systematized for ease of use.

The table shows the average weight values. The possible maximum and minimum values of the mass are respectively 1.3 and 0.7 of its average value
Often when planning construction works, you need to know how much a cube of concrete m300, m400, m500 weighs. Let's see how much a cubic meter of concrete mix will weigh, depending on its type. The mass of the concrete mixture is determined by the mass that the aggregates used have.
Weight m3 of concrete grade M100, M200, M300, M400, M500.
According to the specific gravity, the concrete mixture can be:
- extra light up to 500 kg;
- light 1000 to 1800 kg;
- heavy 1800 - 2500 kg;
- especially heavy 2500 to 3000 kg.
As you can see, when calculating the mass of a concrete solution, there is nothing complicated, and then we will consider in more detail the question of what mass of concrete of different grades, we will also provide detailed tables.
SpecificandVolumeconcrete weight in 1m3, masi table of all grades.
Concrete is the main component of any construction work, whether it is a simple repair or the construction of pits and structures. It has high strength initially, but with the use of additives it can improve in performance.
During construction, first of all, how much concrete weighs is calculated, since on the basis of this characteristic it is determined by the specifics of its use and application. The weight of the solution depends directly on the components added as filling. It can be materials such as crushed stone, expanded clay, pebbles and many others.
Also, when kneading, the volume of water used is also taken into account. On the basis of these characteristics, concrete is divided into four types: light and heavy, extra light and extra heavy.
Weight of 1 cube of concrete of all brands and classes, table:
| Concrete grade | Concrete class | Weight of 1 m3 of concrete (kg) |
| M100 | B7.5 | 2494 |
| M200 | B15 | 2432 |
| M250 | IN 20 | 2348 |
| M300 | B22.5 | 2502 |
| M350 | B25 | 2502 |
| M400 | B30 | 2376 |
Types of specific gravity of 1 cube of concrete.
The most common way to classify the mass of a cube of composition is by division according to specific gravity.
According to the volumetric mass, there are such types of concrete as:
- Particularly lightweight: Weight 500 kg maximum per cube. The content of air cells with a diameter of 1-1.5 mm and a porous base is characterized. These are foam and gas blocks familiar to us, which basically have not only classic cement and sand, but also a foaming agent that creates cells with air. This allows you to create a low weight and good thermal insulation ability.
- Lungs- concrete compositions filled with lightweight porous aggregates, such as expanded clay or without aggregates, but having a porous structure, such as foam concrete or aerated concrete. A cube (cubic meter) of lightweight concrete weighs from 500 to 1800 kg. A cubic meter of concrete includes about 600 kg of sand - the main and indispensable component. Lightweight concretes are usually used as prefabricated building blocks.
- Heavy. This is the most common (classic) type of mortar. It is best suited for the construction of the main elements of load-bearing structures, pouring screeds, erecting fences, etc. The composition of heavy concrete includes large-sized and massive fillers: coarse sand, gravel, crushed stone. It is they who occupy the bulk of the mixture. A cubic meter of such material weighs 1800-2500 kg.
- Particularly heavy. In production, metal fillers are used, which give the finished product a massiveness. The weight of a cube of concrete is 2500-3000 kg. In the composition of super-heavy mixtures, cement of increased strength is necessarily present. In private housing construction they do not apply. Usually, protective structures for special purposes are made from them, for example, for nuclear reactors.
What determines the weight of 1 meter of cubic concrete?
As in any other case, we need to start with theoretical foundations. First, let's find out what, in fact, is this very weight. concrete pavement for every 1m3.
The weight of a cubic meter of concrete, depending on the aggregate:
| Type of concrete, aggregate | Specific weight of the cube, kg |
|---|---|
| Reinforced concrete | 2500 |
| Concrete on gravel or crushed stone | 2400 |
| Tuff concrete | 1200-1600 |
| pumice stone | 800-1600 |
| Concrete on volcanic slag | 800-1600 |
| Expanded clay concrete on expanded clay sand, expanded clay concrete | 500-1800 |
| Expanded clay concrete on quartz sand | 800-1200 |
| Expanded clay concrete on perlite sand | 800-1000 |
| Shungizite concrete | 100-1400 |
| Perlite concrete | 600-1200 |
| Slag-pemzoconcrete (thermosite concrete) | 1000-1800 |
| Slag-pumice foam and slag-pumice aerated concrete | 800-1600 |
| Concrete on granulated blast-furnace slag | 1200-1800 |
| Aggloporite concretes on boiler (fuel) slags | 1000-1800 |
| Ash gravel concrete | 1000-1400 |
| Aerated concrete and foam concrete | 800-1200 |
| Aerated concrete, foam concrete, gas silicate and foam silicate | 300-1000 |
| Vermiculite concrete | 300-800 |
What are the main indicators of the quality of concrete are known:
- strength and durability;
- frost resistance and moisture resistance;
- degree of setting (hardening rate);
- weight of concrete per 1m3.
This, of course, is not all, but the main indicators (all indicators are in guests, tables, if desired). It is important to understand here that the concept of weight per 1m3 is based on the intersection of the concepts of strength and weight. The fact is that the strength and ability to hold different kind the load on the concrete will be based on the density of the product. We already know that concrete blocks are different.
The following two tabs change content below.
WEIGHT OF 1 CUBIC METER (VOLUME WEIGHT) OF BEAM, BOARDS AND MOLDINGS
The weight of lumber (beams, boards, logs), molded products (lining, trim, plinths, etc.) and other wood products depends mainly on the moisture content of the wood and its species.The table shows the weight values of 1 cubic meter of wood (volume weight) depending on the type of wood and its moisture content.
Weight table 1 cu. m (bulk weight) timber, boards, lining made of wood of various species and humidity
Depending on the moisture index, measured as a percentage of the mass of water contained in wood to the mass of dry wood, wood is divided into the following moisture categories:
Dry wood (humidity 10-18%) is wood that has undergone technological drying or has been stored in a warm, dry room for a long time;
Air-dry wood (moisture content 19-23%) is wood with an equilibrium moisture content, when the moisture content of the wood itself is balanced with that of the surrounding air. This degree of humidity is achieved during long-term storage of wood in natural conditions, i.e. without the use of special drying technologies;
Raw wood (moisture 24-45%) is wood that is in the process of drying from a freshly cut state to an equilibrium state;
Freshly cut and wet wood (moisture content over 45%) is wood that has been recently cut or has been in water for a long time.
WEIGHT OF ONE BEAM, ONE EDGING AND FLOORS, LININGS
The weight of one beam, board or any molded product also depends on the moisture content of the wood from which they are made and its species. The table shows the data for the most used wood in construction - pine with damp moisture for timber and edged board and air-dry moisture for floorboards and lining.Weight table of one beam, one board and lining
