Concrete B15 and its use in construction

The basic technical characteristic that influences where the concrete B15 is applied is the strength factor. All other properties will mainly depend on the type of mixture used. For example, with a low concentration of cement, the stiffness parameters may vary. The density of such a composition is characterized to a greater degree by a filler, which is added in the form of calcareous, gravel or granite crushed stone. The latter option is considered to be the most expensive, so with its application, concrete B15 is rarely performed. The price in this case increases to a large extent. If the formula is strictly followed, the content of various impurities and other inclusions is excluded during the preparation.

Unlike heavy analogues, concrete B15 practically does not require the inclusion of special additives. This does not apply only to ingredients that prevent the freezing of the finished mixture. The strength of this composition is considered sufficient for the construction of concrete screeds, the erection of foundations and tracks. Very often it is used in the manufacture of road plates, as well as blocks of FBS. In individual construction it is actively used for pouring various types of foundations and erecting auxiliary rooms.

To date, concrete class B15 has become one of the most in demand in low-rise construction. It is he who becomes an indispensable assistant in the construction of suburban buildings, providing a very good quality for a small price. Thus, the main advantage of a concrete mix of this class is comparative cheapness with excellent strength characteristics.

When building a house or any other building independently, the percentage ratios of the materials used to prepare the mixture must be known. The proportionality of all components plays an important role in the process of foundation construction, because it acts as the basis of any building. To ensure a long life of the entire structure, you should take care of the foundation by preparing the correct concrete B15. Strong foundations are found in strip foundations, but there are options in the form of concrete columns or blocks.

The composition of any concrete mixture includes: water, filler and astringent. Cement is the last ingredient. Getting a quality composition can only guarantee the brand M200 and above, although for a small country house is quite suitable and M150. As a rule, one unit of cement accounts for three to four units of sand and the same amount of filler. When concrete B15 is prepared, the content of other impurities in the form of grass, soil and other foreign inclusions is not allowed. It is desirable to have a concrete mixer in order to mix the mixture qualitatively. Manually to achieve a good result is problematic enough. All components that make up the composition are all-grain materials, which, without fail, must evenly fill all voids.
