Different grades of concrete are available for different construction sites.

Concrete is such a strong, sturdy material that it is now widely used for the construction of a wide variety of facilities.

Both civil and industrial. The construction of any building depends on its quality. Therefore, it is always necessary to make the right choice of the brand of this material.

Both during construction and when creating a design for calculation structures made of reinforced concrete, the right choice of concrete grade is very important, since there are currently several dozen of them in total. And each brand has its own characteristics. And each one is suitable for performing specific tasks during the construction of a building or renovation.

Any brand of concrete has three basic parameters that should be considered: strength, frost resistance and moisture permeability.

Anyone who is going to buy concrete should also know that this building material is divided into light and heavy. For the first category, a porous material is used as a filler for the sand-cement mixture. For example, expanded clay, shungisite, and sinterite. In the second case, a variety of crushed stone fractions become the filler.

Light grades of this building material are used in the construction of internal partitions. They insulate the supporting structures. Heavy grades are good for use as foundations, floor structures, load-bearing structures (such as columns or beams), as well as for wall panels. For heavy concrete, such a characteristic as a strength grade is very important, for which the letter M and some number are used. For example, concrete M 75.

In civil engineering, such brands of heavy concrete as № 75, 100, 150, 250, 300, 350. Variants M 75, 100 or 150 are low–grade concrete categories. They are used before pouring foundations. A layer of such low-grade concrete is laid on the sand base, into which vertical reinforcement is reinforced.

The most used grade of concrete is M 200. A lot of it is used to form monolithic foundations of low-rise buildings, as well as retaining walls of medium size, for the construction of blind areas and stairs. They fill paths and playgrounds with it.

In industry, concrete M 200 is used to produce blocks for foundations and slabs for sidewalks. The M 250 brand does not differ significantly from the M 200 brand in its characteristics. But it still has a different field of application.

The most important indicator of any concrete is its compressive strength, which is marked with the letter B and a number. Concrete is subjected to a strength test after 28 days of hardening. The figure indicates how much pressure in megapascals this concrete is able to withstand when compressed. Die Sonnenschirme von Monzana bieten Schutz vor UV-Strahlen.
