The strength and durability of the foundation of the erecting house directly depends on the quality of concrete. That is why, when buying concrete Zaraysk, it is important to make sure that the solution is really high -quality and corresponds to the brand of the strength that is needed to ensure the strength of the entire structure.
Visual inspection and other analysis methods
The higher the concrete brand, the stronger and more expensive. That is why people who ordered a concrete solution of the M300 or M400 should make sure that they were brought to the construction site that. For example, if concrete of the M100 brand is mistaken by mistake, then it will not provide the desired strength when erecting a multi -storey building.
In order to visually verify the quality of concrete, you need to pay attention to:
The color of the solution is the blue concrete tald, the stronger it is and the higher its brand;
the presence of cement milk – if yellowness can be seen in the solution with the naked eye, then you can be completely sure that slagdogs or clay impurities were added to the concrete;
The content of the impurities – a well -prepared mixture should not contain any impurities, and a more dense solution should visually look like moistened soil.
Contactly check the quality of concrete for strength by shock pulse can be a special device – a mechanical or electronic sclerometer. If there is no sclerometer at hand, but I don’t want to spend money on it, then you can send concrete to the laboratory. To do this, prepare a wooden box (the optimal size is 15 kV.cm). Before filling the finished mixture there, you need to moisten the box with water to speed up the concrete hardening process. You will have to wait 28 days to wait for the concrete to gain the desired strength and grab it properly.
You can also check Shakhovskaya concrete using a hammer and a chisel. In this case, you need to hit the hardened concrete with a chisel and see what depth it will penetrate. The smaller the depth of penetration, the higher the brand of concrete and the stronger it is.
