Investigation of the Porous Structure of Concretes Treated with Polymer Silicate Compositions with Nanoadditives

The influence of nanoscale and fine-dispersed additives on the properties of protective impregnating compositions during the restoration of the structure of various materials, including concrete and ground concrete, which is very important for the reliable operation of the operated structures, has been studied. The study notes that during operation, the total porosity of materials changes dramatically and increases, and this leads to the decommissioning of building elements or their condition is recognized as unsatisfactory. Methods of protection of various materials on a mineral bundle with protective impregnating polymer-containing compositions with nanoscale additives aimed at prolonging the service life of structures, buildings and structures are considered. The necessity of preventive measures at the design stage of structures, as well as primary and secondary protection of materials from corrosion and aging, including, respectively, the introduction of various modifying additives, including nanoscale ones, into their composition, is noted. In addition, the study of physico-chemical processes in systems with protective impregnating compositions made it possible to optimize their rational consumption and obtain effective means to extend the service life of various objects.
