The results of the researches on the development of wear resistant polymeric composite materials on the base of polytetrafluorethylene and activated basalt fibre are represented. The effectiveness of the usage of activated basalt fibre for acquisition of the materials with increased wear resistance without the reduction of the physical and mechanical characteristics is showed.

The article presents the results of the investigations aimed to relate variation in energy consumption of fined-grained concrete destruction, content of basalt fiber and cyclic freeze-thaw effect. The energy consumption of fine-grained concrete destruction was determined using the vertical impact testing machine by Syskov, the reinforcement of concrete was basalt fibers with a diameter of 23 μm and 6 mm long. Concrete samples saturated with sodium chlorite solution were subjected to cyclic freeze and thaw by the third rapid method (freezing temperature 50±5°С) as per state standards GOST 10060.0-95 and 10060.2-95. It is found that dispersed reinforcement of fine-grained concrete with basalt fibers increases energy consumption of concrete destruction up to 1.8-1.9 times. The fiber-reinforced concrete samples are capable to resist impact loading after effect of alternating temperature. After 5 freeze and thaw cycles, reduction in the energy consumption of nonreinforced concrete destruction reaches 58% of initial value...

The article presents some research findings on the effect of basalt fiber 6 mm in length with a diameter of 23 μm on strength of fine-grained concrete (cement-and-sand matrix) under bending, compression and alternating thermal forces. It is found that the maximum increase in the bending strength of concrete by 31-36% is reached at the fiber content of 4-6% of dry mixture weight (cement+sand). There is no considerable increment in the compressive strength; moreover, at the fiber content of 6%, the compressive strength decreases by 16% as compared with the initial (non-reinforced) specimens. Exposure to 5 accelerated freezing-thawing cycles (freezing temperature 50±5°С, State Standard GOST 10060.2-95) resulted in the reduction in the bending strength of non-reinforced specimens by 73% as against the untreated specimens whereas the strength of the specimens with the fiber content of 2 and 4% lowered by 40 and 35%, respectively. In the compression testing, 5 freezing-thawing cycles decreased the strength of the check non-reinforced specimens by 47% while the decrease in the strength of the reinforced specimens with the fiber content of 2% made 5% as against the check specimens, which corresponded to the freeze resistance grade F200 in compliance with GOST 10060.2-95. The obtained results prove that disperse reinforcement of fine-grained concrete with basalt fiber can increase freezing resistance of concrete and its resilience under bending and compression, which expands application field of concrete.
