PAINTS WITH INCREASED WATER RESISTANCE TO PROTECT CONCRETE BUILDING STRUCTURES OF HYDRAULIC FACILITIES

Abstract

For concrete and reinforced concrete structures of hydraulic structures of the Republic of Belarus, the conditions of their operation in fresh water are of paramount importance. The aim of the work was to develop formulations of paints based on polymers with different glass transition temperatures and different ratios of methyl methacrylate and n-butyl acrylate in the polymer, which have low water absorption and increased resistance to water. This would allow them to be used to protect concrete and reinforced concrete hydraulic structures. Laboratory tests of paints have shown a direct dependence of the physical and mechanical properties of protective coatings based on them on the composition and physicochemical properties of acrylic copolymers. The correct choice of design and engineering solutions, the joint work of designers and corrosion specialists allows to minimize the corrosion load on hydraulic structures.
