Studies of gravy of concrete mixture of equipment carried out by VNIIMOSTAZPETSSTROM showed that the shrinkage of concrete is small and it can be neglected, especially since the shrinkage process lasts more than a year and the deformation occurs evenly along the entire surface. There is no sediment in hard concrete, and in plastic ones it is about 0.1 mm per 100 mm of the grave thickness.
