Abstract: The compressive and flexural behavior of basalt fiber reinforced fast setting and hardening concrete is investigated with the content of basalt fiber from 0.1% to 0.3% by volume. The cubic compressive strength and the stress-strain curve under bending state are measured by a dynamic strain indicator, and the cubic compressive and bending strength of concrete with three different water-cement ratios: 0.4、0.45、0.5 are also compared. The results show that the addition of basalt fiber can enhance the compressive strength of the fast setting and hardening concrete to a certain extent, and at the same time can improve its flexural tensile strength from 5% to 20%. The stress-strain curve exhibits a significant yielding limit of basalt fiber reinforced fast setting and hardening concrete specimen. The ultimate tensile strain of four-point bending test can reach 650×10-6～935×10-6.
