Abstract

Abstract: This article examines the influence of drying, vacuumizing and monomers polymerization on concrete strength in saturated concrete structures. There are different methods of drying concrete, such as: convective, radiation (including infrared), contact (preferably electric) and microwave (high-frequency). Impregnating monomers used for various purposes tasks to protect and enhance designs, longer service life. It was shown that the kinetics of strength growth and the stress deformation state of the concrete is complex and depends on many factors, including basic: the composition and type of cement, water-cement ratio, the rate of temperature increase, humidity and more. The modes and methods of concrete impregnating by monomers and polymers in view of the size of molecules injecting material and type of concrete are described. Of great interest is the partial or surface  impregnation of concrete and reinforced concrete structures that serve to improve the filtration characteristics and corrosive resistance of material. The influence of temperature on polymerization and strength of structures and the impact of radiation polymerization of monomers in the body the strength of concrete structures. The attempt to build a mathematical model of the polymerization of monomer in the pores of the concrete. It is the process of polymerization in capillary-porous media is a process blokovoyiyi polymerization. It is shown that some of the problems of technological factors insufficiently studied.
