ANALYTICAL REVIEW OF RESEARCH PHIZIC-MECHANICAL PROPERTIES OF CONCRETES WITH VOLUME HYDROPHOBIZATION

Concrete protection with the help of hydrophobical additives has been used since 60–70, but with increasing requirements to the durability of structures, their corrosion resistance and the appearance of new types of hydrophobical additives on the market, it becomes necessary to thoroughly investigate their effect on the physical and mechanical properties of the cement stone and possibly expand the scope of their application in the construction industry. Goal and tasks. Analyze the main trends of research related to volumetric hydrophobization of cement stone, which were obtained in recent years. Conclusions. Organic silicon compounds are optimal for improving the basic properties of concrete and can be the basis for a complex of materials, with synеrgetic action of which will lead to the production of concrete with high hydrophobical and cost effective properties. Hydrophobic additives with colmatating effect are the last generation's foreign-made impurities, and require thorough research on their impact on the cement of Ukrainian production and the properties of concrete.
