This extra reinforcement is necessary because the tensile strength of concrete (in direct tension) is only about 10% to 15% of its compressive strength, so 3,000-psi concrete might have tensile strength of only 300 psi, compared with grade 60 steel, which has tensile strength of 60,000 psi. When a load is applied to a concrete beam, it …

Basalt fibre reinforced concrete finds its application in building earthquake-proof structures, explosion hazardous facilities, reservoirs and concrete pipes ...
The thickness of the concrete cover ( αs) was 45 mm. The length of the specimens was 1700 mm and the net span was 1400 mm. The effects of the basalt fiber volume ratio and reinforcement ratio on the flexural properties of the test beams were studied. The volume ratios of basalt fiber were 0.1, 0.2, 0.3 and 0.4% respectively.

Abstract. Basalt fibre reinforced polymer (BFRP) rebar is an emerging green construction material. In this research, performance of concrete beams reinforced with BFRP rebar has been evaluated. Full-scale tests on eight large-scale concrete beam specimens reinforced with either BFRP rebars or steel rebars were undertaken.
The inclusion of basalt fibres significantly enhances the modulus of rupture, whereas there is no significant effect on compressive strength. Compared with control concrete, the mechanical characteristics of concrete reinforced with 1.5% by volume of basalt fibre increase by 4.45%, 22% and 57% respectively. 1.
