Abstract
Relevance. Basalt fibers are increasingly studied in structural applications due to its environmental friendliness, good mechanical properties, thermal and chemical resistance. The aim of work. Mass production of high-strength concrete in Russia is mostly associated with the use of organomineral modifiers of the MB series, which consist of composition microsilica, fly ash, hardening regulator and superplasticizer C-3 in various proportions. The purpose of the experimental research is to study the effect of basalt fibers in high-strength concrete. Solution technique. The research of physical and mechanical properties of basalt-fibered high-strength concrete was made on samples with detentions of 100×100×100 and 100×100×400 mm with the use of modifier MB10-30C. The compressive strength, the tensile strength at bending, the strength at axial tension, and the cracking moment in various periods of curing (after 7, 14, 28 and 60 days of curing) were determined under the research. Results. The research results show that the use of basalt fibers in high-strength concrete resulted in a decrease in the compressive strength about 18-20 %, however, enhance the tensile behavior about 42-48 %.
