The basic technical characteristic affecting where concrete B15 is used is the strength factor. All other properties will mainly depend on the type of mixture used. For example, at low cement concentrations, stiffness indicators may vary. The density of this composition is characterized to a greater extent by the filler, which is added in the form of calcareous, gravel or granite crushed stone. The latter option is considered the most expensive, so concrete B15 is rarely performed with its use. The price in this case is increasing significantly. If you strictly follow the recipe, then the preparation process excludes the content of various impurities and other inclusions.
Unlike heavy analogues, concrete B15 practically does not require the inclusion of special additives. This does not apply only to ingredients that prevent freezing of the finished mixture. The strength of this composition is considered sufficient for the installation of concrete screeds, the construction of foundations and paths. Very often it is used in the manufacture of road slabs, as well as FBS blocks. In individual construction, it is actively used in the pouring of various types of foundations and the construction of utility rooms.
To date,
concrete of class B15 has become one of the most popular in
low-rise construction. It is he who becomes an indispensable assistant in the construction of suburban buildings, providing for a low cost quite good quality. Thus, the main advantage of this type of concrete mix is its comparative low cost with excellent strength characteristics.
When building a house or some other building on your own, the percentages of the materials used to prepare the mixture should be known. The proportionality of all components plays an important role in the process of building the foundation, because it acts as the foundation of any building. To ensure the long service life of the entire structure, you should take care of the base, having prepared the concrete B15 correctly. Strip foundations have good qualities, but there are options in the form of concrete columns or blocks.
The composition of any
concrete mixture includes: water, filler and an astringent. The last ingredient is cement. Obtaining a quality composition can only be guaranteed by
the M200 brand and above, although the M150 is quite suitable for a small country house. As a rule, there are three to four sand units and the same amount of aggregate per cement unit. When concrete B15 is prepared, the content of other impurities in the form of grass, soil and other foreign inclusions is not allowed. A concrete mixer is desirable to mix the mixture efficiently. Manually achieving a good result is quite problematic. All the components that make up the composition are different-grained materials, which must necessarily evenly fill all voids.
