Concrete is a popular building material used in the construction of a wide variety of buildings and structures. Its different types have different characteristics, primarily weight.
How much does concrete M300 weigh
In general, the spread in the mass of concrete is very large - from 500 kg / m3 to 2500 kg / m3. And according to this important indicator, the material is divided into light, medium and heavy types, which have slightly different areas of application.
M300 concrete belongs to the heavy type and weighs on average 2300-2500 kg / m3. It is used for the construction of various structural elements:
- carriers and itself load-bearing walls, partitions, ceilings, building foundations;
- for subfloors, paths around the house and on the plot, entrances to the house from the main road, etc.;
- for hydraulic structures;
- in road construction.
How to determine the weight yourself
You can roughly calculate the mass of a cubic meter of concrete M300 knowing the weight of all the components used concrete mix... However, it should be understood that 1m3 of the finished mixture will go somewhere 20-30% more by volume of the components. This is due to the fact that during the preparation of the mixture, it is strongly compacted, cement and sand occupy the previously empty spaces between the grains of the coarse aggregate. If this is not just concrete, but a reinforced concrete structure, then when calculating the weight, it is worth taking into account the weight of the steel reinforcement used.
Also, the weight indicator will not necessarily be constant for a particular brand of mixture. It can vary quite a lot depending on the raw materials used (sand, cement, crushed stone), their density and size. So, for example, the use of a coarse aggregate increases the number and size of pores in a concrete stone, thus making it lighter.
The weight depends on the type, quantity and size of the aggregate (sand and crushed stone) and only shows what kind of load this concrete element creates, transfers to the supporting structures and then to the base soils. He does not give a direct indication of strength. It mainly depends on the grade of cement that was used (it should be 1.5-2 times higher than the desired grade of concrete), and is indicated in the grade of concrete - the numerical coefficient shows the compressive strength in kg / cm2 of a cubic sample (with edges along 15 cm) of this concrete. Those. in the case of the M300 brand, a concrete cube, having gained almost 100% strength on the 28th day of hardening, must withstand 300 kg for each square centimeter of its surface.
Cement mortar is one of the most popular materials in construction. When erecting any structures, it is important to take into account the specific gravity of the substances used. For example, if a construction site involves the use of cement, then you need to know how much a cube of concrete of a particular configuration weighs. Reinforced concrete and concrete structures are the basis of many buildings, so it is impossible to neglect their properties at the design stage.
Weight classification
Concrete mixes are used in quite a variety of ways. Modern cement is necessary for such operations:
- interior decoration of living quarters;
- construction of reinforced concrete foundations of buildings;
- erection of dams and monolithic structures.
It is used for other purposes as well - this is just a rough list that shows the variety of uses for this material. Of course, from cement to interior decoration and building the foundation requires different characteristics, which is why all mixtures are divided into classes and brands.
Using the classification, you can also determine the weight of 1 cube of concrete. The mass increases with a change in type:
- heat-insulating (especially light, classes below B7.5);
- easy (grades B7.5-B15);
- heavy (B15-B30);
- heavyweight (more).
The first includes brands from M50 to M75, their specific weight does not exceed 500 kilograms. To the second - from M100 to M200, which range from 500 to 1800 kg. "Heavy" ones are marked as M200-M400, and their specific gravity is 1800-2500. All brands from M450 are considered especially heavy. The specific gravity of such concrete reaches three tons.
Thermal insulation mixture
Such a cement contains a large volume of fillers, due to which a level of 85% of voids is achieved. Although the mass of a cubic meter of such a mixture does not reach half a ton, and in a frozen state, it cannot withstand heavy loads and perform a load-bearing function, the brand has the lowest values of thermal conductivity. Porous structures do not withstand cold well and wear out quickly under the influence of frost, therefore, to increase strength, a plasticizer for concrete is also included in the mixture. The instability of moisture should not be ignored, which is why the installation of waterproofing is mandatory.
Medium types
"Light" mixture is not uncommon, especially M150. Many types of ready-mixed concrete are in the range of 500-1800 kg specific gravity. Most building blocks have pores in their structure. Air bubbles in the mass are created using foaming agents or cellular fillers. Among the latter, expanded clay is often used.
"Heavy" concrete is used much more often than other types, because it is used for the construction of many components of the structure. First of all, it is used for parts that perform a load-bearing role. A cube of concrete M300 weighs at least 1800 kilograms - this applies to all mixtures belonging to the heavy type. If it becomes necessary to make the supporting structure stronger, the density is increased to 2.5 tons per cubic meter. This is done by changing the ratio of sand and coarse filler. The density of the latter also plays an important role - gravel crushed stone is much heavier than granite or expanded clay.
Extra heavy concrete
This species is not widespread due to its specificity. Such concrete can reach maximum values when one meter cube weighs about three tons. To achieve such indicators, metal fillers are included in the mixture, many of them are relatively specific materials for the construction industry. They are also quite expensive. But the M450 brand perfectly prevents the spread of radiation.
Particularly heavy concrete is used only for the construction of special structures. Walls made from dense mixtures with metallic impurities reflect most of the radioactive radiation. This is beneficial for the construction of nuclear power plants, laboratories and "sarcophagi" in the field of disasters associated with the release of radiation.
Volumetric and specific gravity table
Volumetric weight is calculated during transportation and differs from the actual one. The density depends not only on the brand, but also on the state of the mixture (liquid or dry).
As it becomes clear from the table, the weight of concrete per 1 m³ in a liquid state is higher than in a dry state.
The values always differ, how much 1 cube of concrete in kg weighs actually and calculated. The real values are shown in the second table..
If you compare these two tables, you will notice that the estimated weight of the M200 brand is equal to the actual mass of the M250 cube. This also applies to other species. How much does a cube of concrete M300 actually weigh, as much as M250 according to calculations.
Attention! The exact correspondence of the described characteristics to the specified brand is achieved only with the factory production of the mixture.
In this article we will look at how much a cube of concrete M300 weighs. Such information will be very useful in planning the foundation, calculating the strength of the future structure and transporting the mortar itself. But let's talk about everything in order.
General Provisions
Concrete of the three hundredth grade is very widespread in construction:
Application area
- any structure... The material in question is equally well suited for creating a strip, monolithic and even pile foundation.
- Construction of load-bearing walls and partitions... We are talking about both residential premises and utility buildings.
- Creation of a sub-floor, stairs, garden paths and other structures requiring increased strength.
Reasons for the demand
What properties make this solution so popular?
- , allowing to withstand significant pressure and strong mechanical stress. High grade concrete is used even in the construction of military bunkers.
- Moisture resistance, preventing destructive processes resulting from penetration and exposure to water.
- Acceptable price. All ingredients are readily available and are not expensive.
- The ability to create with your own hands at home, which allows you to save the family budget on ordering a ready-made solution.
Tip: when mixing at home, it is recommended to use a concrete mixer.
It will help to achieve the desired homogeneity of the solution and simplify the process.
- Long operational period, measured in decades.
Weight search
From the scope and strengths of this material, it follows that it must be composed of ingredients with high strength characteristics. Let's then take a closer look at the components that form the weight of the M300 concrete cube.
Composition
The proportion of the components is strongly influenced by the brand of cement used, which should not be lower than four hundredth.
Thus, the instruction offers the following options:
- M400: cement / sand / crushed stone / water - 1 / 1.9 / 3.7 / 0.5;
- M500: cement / sand / crushed stone / water - 1 / 2.2 / 3.7 / 0.5.
Advice: in case of using wet sand, it is recommended to reduce the amount of added water. Otherwise, the solution may become too thin.
Now let's analyze the table with numerical values:
Approximate weight
Even taking into account the above data, it is difficult to determine exactly how much 1 cube of M300 concrete weighs.
There are many factors to keep in mind that have a significant impact on the weight-to-volume ratio:
- The fine aggregate is designed to eliminate the pores that form between the coarse aggregate fractions, but 100% success is not possible.
- The coarse filler itself can have different porosities, depending on the quality and origin. Especially if, in an effort to lower the coefficient of thermal conductivity, it is used instead of crushed stone and gravel, for example, expanded clay.
- Evaporation of water. So for solidified and fully formed concrete, its weight can be practically ignored. But, even when dealing with a solution, one should remember about a constant decrease in the amount of moisture in it, which also affects the total mass.
Approximately, you can already make theoretical assumptions about the weight of 2200-2400 kg. Let's add some practice. Some companies carried out experimental weighing not only of the three hundredth grade we are considering, but also of other popular concretes, and here is what data they received:
The weight of 1 m3 of concrete M300 equal to 2389 kg fits into our approximate calculations based on the ingredients used in mixing the mortar.
Additional influence
If you are laying a strip foundation under a reinforced concrete wall and want to take into account its weight as accurately as possible, then you should include in the calculations all the reinforcement used to strengthen the strength of the structure. Although the water will evaporate, the metal will more than offset its weight, and will also exert significant pressure on the base.
Conclusion
Having an idea of the weight of the concrete used, in our case it is M300 grade mortar, you will be able to better design engineering work and strengthen the foundation sufficiently. The main thing that you will need to carry out the calculations is the exact proportions of the ingredients used and their mass. It is also advisable to take into account all additional factors affecting the porosity of the material.

How much cement is needed for 1 cube of concrete for a foundation? How many liters are in one cubic meter? 1m3 = 1000 liters or 1 liter = 0.001m3. How much cement, sand, crushed stone in a cube of concrete? - The concrete mix traditionally consists of three components mixed with water - cement, sand and filler.
And the difference in weight between them varies significantly. Conventional concrete mixed from composite - cement, sand, water and filler (gravel or crushed stone), will vary in weight from 1800 kg to 2500 kg, and it will depend on the volumetric weight of the filler. Filler (gravel or crushed stone) - 1200-1300 kilograms.
More sand and cement will be consumed - if the filler is larger and less - if finer. Different brands of concrete weigh differently. There can be no definite answer here, since there are several types of concrete, the difference is in the brand of cement, filler, additives.
1 m³ = 1000 dm³ = 1,000,000 cm³ = 1,000,000,000 mm³ = 1000 liters ≈ 35.3 cubic feet ≈ 1.31 cubic yards ≈ 6.29 barrels. For heating a cubic meter of water from +1 to +100 degrees Celsius at standard atmospheric pressure requires about 100,000,000 calories (100,000 kcal = 100 MKal) or 116.299 kilowatt-hours.
In fact, during the year of its activity, LLP removed 15,166 m3 (cubic meters) of solid household waste (garbage). In any case, during the trial (if you intend to appeal this act), you could demand a calculation formula and legal basis for these calculations.
It is important for me to know if there are GOST standards in force in the Republic of Kazakhstan on these issues. The weight of a cubic meter of solid waste depends on its density. There is a draft of the state standard "METHOD FOR DETERMINING THE MORPHOLOGICAL COMPOSITION OF SOLID HOUSEHOLD WASTE". Is it possible to clearly answer this question and why are different units of measurement of the same building material used?
Only an experienced builder can clearly calculate the ratio of the initial components, therefore, if you are not sure about the proportions, it is advisable to contact a specialist for help. If we are talking about crushed stone packed in bags (regular or colored), the unit of measurement will be kilograms.
And vice versa: the weight of a cubic meter of fine gravel or granite screenings will be at least a hundred kilograms more. So, for example, a cubic meter of crushed limestone weighs about 1300 kg, gravel - 1600 kg. However, this knowledge is not enough to start a certain construction.
In addition, liters in our country have not become a generally accepted "production" and trade unit for measuring volume. One cubic meter, or in an abbreviated version - one cube, turned out to be a rather convenient and popular unit of volume for practical use.
How much does a cubic meter of crushed stone weigh?
After all, their cost, prices, rates, consumption rates, tariffs, supply contracts are almost always tied to cubic meters (cubes), much less often to liters. Site visitors, asking how much 1 cube weighs, often indicate specific units of mass in which they would like to know the answer to the question. Density and specific gravity in physics are usually measured not in kg / m3 or in tons / m3, but in grams per cubic centimeter: g / cm3. Garbage density and specific gravity are given in Table 1 as additional information.
The amount of cement in 1 cube of concrete
Let's start with the fact that all units of measurement used on this moment in physics, and in ordinary life, this is the result of centuries of experimental decisions. As a result, in order not to be confused in all pounds, miles, inches, it was decided to come to uniform measurement values.
Through simple reflections, we come to the conclusion that 1 liter of water weighs 1 kilogram. It should be noted that in the overwhelming majority of countries these metrics are accepted as basic, sooner or later, but accepted.
Cubic Meter - means a unit of volume of dry Gas equal to one (1) cubic meter at a temperature plus twenty degrees Celsius (20 C) and a pressure of one absolute atmosphere. How many cubic meters of acetylene and water is required to obtain 45 tons of 98% acetaldehyde by the Kucherov reaction.
About 1.2 kilograms of air. This year my wife and I decided to move to a permanent place of residence in Vologda. Good afternoon. I have a dacha in my village and I already want to make new plaster there, but before I do it, I would like to read a little about it.
How to fit everything you need in the bathroom? How many bags will it take?) This is a question for the builder. From the right choice the cementing component of the mortar depends on the cement content in one cubic meter, practicality with the consumption of concrete.

When calculating cement per cube of concrete, the weight of the dry composition is taken as the basis. The question of how much a kilogram of concrete is in a cube is more relevant when preparing estimates and determining the type of transportation. How much cement is in a cube of concrete - the calculation is very individual and requires the most serious approach. In one cubic meter of this type, the mass is not more than 500 kg. There is a not entirely correct opinion that the greater the specific or volumetric weight of concrete, the higher its strength.
Concrete is an integral part of renovation or construction. He has high rates strength, ease of use and provides buildings with durability and reliability. One of the main technical characteristics- the mass of concrete in one cube. Its value makes it possible to assess 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 are different in the ratio of components, structure, and most importantly, in specific weight. Before starting construction, you need to make a careful calculation of materials, and the question often arises, how much is a kilogram of concrete in a cube of concrete?
Separation by specific gravity
- Especially 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). Mesh size - up to 1.5 mm. The mortar 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.
- Lightweight - 500-1800 kilograms per cubic meter 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 mixture, blocks are made that make up the partitions of the walls, lightweight structures.
- Heavy - 1.8-2.5 tons per cubic meter. They can contain large rocks - gravel and crushed stone, as well as coarse-grained sand as an aggregate. In addition, the mass of the material includes up to 200 liters of water, cement (250-450 kg). This type is the most popular, has a wide range of applications: from load-bearing structures to concrete foundations.
- Especially 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 their wide range of applications. They have several brands with different proportions of components. The most common ones are listed below:
- Grade M100 - specific gravity 1 m3 = 2494 kg. Main application: preparatory, pavement construction, curb installation.
- The M300 brand belongs to the class of heavy concrete. Weight varies from 2.2-2.5 tons per 1m3. M300 is used for the manufacture of monolithic foundations, fences, walls, flights of stairs, floor slabs.
