Extended Abstract:Disperse fiber reinforcement is used to improve deformation and shrinkage
characteristics, flexural strength of concrete. Basalt roving and thin staple fiber are often used as mineral fibers. The paper considers the problems of using thin basalt fiber produced by centrifugal-blow method. Evaluation of the corrosion resistance of basalt fiber as part of the cement matrix was performed. Nanodispersed silica produced by electron beam accelerator was used to increase corrosion resistance of basalt fiber.
Key words:disperse fiber reinforcement, basalt fiber, nanosilica, corrosion resistance, compressive strength, flexural strength.
