Concrete with a complex additive based on a superplasticizer and an organosilicon polymer

Abstract

Depending on the functional purpose, different requirements are imposed on the products. In particular, reinforced concrete products used in irrigation and drainage construction, along with increased strength and frost resistance, are required to have increased water resistance. For the water resistance of concrete, through macropores (filter capillaries) are dangerous, which are formed as a result of uneven thermal expansion of concrete components during heat treatment, as a result of plastic shrinkage and sedimentation during compaction. The relationship between the structure and impermeability of concrete is very complex.
