Polymer concretes (PC) unlike common concrete (produced based on cement, as cohesive material) are notable for the high durability on compression - 50...90 MPa, and especially, on tension - 6...10 MPa, with unique corrosion resistance. However, they are also associated with such negative properties, such as high deformability, creep. Because PC works well on tension, their application is perspective for production of shock resistant construction material, but for this, it is necessary their strengthening by additional reinforcing mechanisms. In addition, because of the differences in the durability and deformability on compression, as well as on tension, is important that stipulates the necessity of reinforcement of PC tensile and bent elements. This work presents and discussed the reinforcement of PC by hybrid fibers. The major goal of this work is the production of such hybrid fiber-reinforced polymer concrete (HFRPC) with high durability on tension and high shock resistance that preserves these properties in conditions of aggressive environments. The primary cohesive methods are unsaturated polyester resins, as polymers. The fiber reinforcements (course and fine) are primarily basalt and steel fibers, andesite selected for their chemical resistance and durability the technological parameters for the production and processing of nano and ultrafine dispersive powders from the rock using vibration and planetary mills, and the physical and mechanical properties of these concretes are presented and discussed. The data on the corrosion resistance coefficient of these processed PC (corrosion resistance coefficient - Kcr, diffusion coefficient of aggressive liquids - Kd) is also presented and discussed.
