The density of concrete: types of material and scope

Concrete is one of the most popular materials used in modern construction. It is quite durable, has good technical characteristics and, in combination with reinforcement, allows the construction of structures subjected to increased loads. The density of concrete M200, makes it possible to use it as a structural material, when other brands have parameters that allow them to be used in other areas of construction.

Different types of materials and their characteristics

To begin with, it must be said that this material has a number of different parameters and characteristics. At the same time, the density of reinforced concrete and other products based on this mixture is considered a fundamental criterion when choosing a specific type and brand. That is why it is worth considering separately.

Lightweight concrete

First of all, cellular materials can be attributed to this type. At the same time, the density of aerated concrete is actually on the verge of these types, since it is equal to 400 to 500 kg per cubic meter.

Although the strength of the blocks from it can withstand quite high loads.

• This fact is often silent sellers, because some buyers often confuse this option with the strength. The fact is that the density of aerated concrete blocks is lower than that of foam concrete products, but thanks to its manufacturing process and subsequent processing, it turns out to be stronger.
• It must be said that there are certain criteria by which this type of material is evaluated.. Typically, the density of lightweight concrete fits in the parameters from 500 to 1800 kilograms per cubic meter. However, its rare species reach the upper limit.

• It is believed that the density of foam concrete can reach a value of a thousand, but in practice bringing the composition to such characteristics is simply meaningless.. This leads to high costs without increasing strength.
• It is important to note that similar formulations include mixtures that include fillers with already established characteristics.. For example, the density of lightweight aggregate blocks depends on the main element used in its manufacture.

• Also to these types of concrete can be attributed products based on perlite, wood concrete and varmikulita. They are not cellular materials and their parameters are closest to the upper boundary.
• If we talk about the density of asphalt, it is worth noting that among similar compounds also exist light mixeswhich are usually represented by components that do not need to be laid using a roller.

• Special attention should be paid to concrete grade M100. The fact is that its density corresponds to type B7 5, which also relates it to light materials, although it does not have additional inclusions.

Tip! Do not underestimate the strength of structures made of such concrete, since in this case it does not always have to do with density. It all depends on the selected material and its individual qualities.

Heavy concrete

This type of mixtures is classified as ordinary. The density of the concrete mix should be from 1,800 to 2,500 kilograms per cubic meter, which is already determined on the finished product. It should be noted that the longer the structure is placed after its filling, the higher this parameter will be.

It is important to mention that there is a special GOST for similar products. It describes all the characteristics of the selected brand and its varieties in accordance with the additional additives used.

There is also documentation describing the density of claydite-concrete and perlite-containing products, which by their parameters approach heavy types of these products. However, professional craftsmen are accustomed to refer such compositions to light species and treat them very carefully.

Tip! Usually the density of such compounds increases with their brand. Therefore, it is very important to know the range of this product and its characteristics.

Particularly heavy concrete

This type of material is almost impossible to create with your own hands at home. Its density exceeds 2500 kilograms per cubic meter.

This is achieved through the use of special additives, special cooking technology and appropriate fillers. It includes limonite, magnetite and barite mixtures.

Tip! All formulations of this type are manufactured under strict control and using express quality control methods. Therefore, the sale of documents are provided with an indication of the exact parameters.

Application area

Given the characteristics of the mixture selected for construction, its scope is also determined. Rather, it is precisely under certain work that the type of material used is selected.

Lightweight concrete

• Some types of this material are used to create light foundations. This applies to aerated concrete and materials with strength B7.5.
• Also, the price and parameters of cellular products allows them to be used for the construction of walls, which have good parameters for keeping heat indoors. However, it is worth remembering that buildings with a height of more than two floors can only be made of aerated concrete.
• Special attention is paid to these types of concrete when creating the screed. They provide an inexpensive and durable coating with excellent thermal conductivity.

Tip! Even cellular types of products are not always good insulants and need additional protection from the cold.

Heavy concrete

Usually the question of how to calculate this parameter for this type of material is connected with the ignorance of brands and their characteristics. Therefore, for each type of work a particular type of product is selected.

However, if we take into account the good density of even the brand M 200, then this concrete is perfect for almost all types of construction work, ranging from pouring the concrete foundation and ending with floor slabs. Higher types of mixtures are used for industrial purposes or in particularly sensitive areas.

Tip! Select a specific brand must be guided by the instructions of the project. You should not look for substitutes or artificially strengthen the material.

Particularly heavy concrete

This type of mixture is used mainly in the construction of nuclear power plants. The fact is that in addition to its high strength and density, it has the ability to retain ionizing radiation. That is why the requirements for its quality and compliance with the specifications are very high, as required by the installation instructions.

Conclusion

After reading the video in this article, you can get more detailed information about this option concrete mixes. Also based on the text above, it is necessary to conclude that the area of ​​its application directly depends on the density of this material.

Special attention should be paid to the fact that the average density of concrete is an approximate indicator, which also depends on the method of installation. Therefore, all castings are made in strict accordance with technological processes.
