摘要

摘要: 为研究钢纤维、橡胶粉掺量对混凝土拉、压和冲击性能的影响，制作了不同钢纤维掺量（0%、0.5%、1.0%、1.5%）与不同橡胶粉掺量（0%、5%、10%、15%）的钢纤维橡胶混凝土试件，其中8组48个立方体试块用于抗压、劈裂抗拉强度试验，8组24个棱柱体用于受压应力-应变全曲线试验，6块板试件用于抗冲击试验。试验结果表明：随着橡胶粉掺量增加，混凝土抗压强度下降；当橡胶粉掺量一定时，钢纤维掺量达到0.5%后对橡胶混凝土的抗压强度、抗冲击韧性影响不大，但能提高其抗拉强度，提高的幅值为7%~28%；1%钢纤维掺量和10%橡胶粉掺量为钢纤维橡胶混凝土性能最优的掺量；建议的钢纤维橡胶混凝土受压应力-应变关系与试验数据吻合较好。

Abstract: In order to study the static and dynamic impact properties of concrete with different contents of steel fibers and rubber powder, 8 groups of 48 cubic specimens were designed for compressive and splitting tensile strength tests, 8 groups of 24 cubic specimens were designed for compressive stress-strain curve test, 6 slabs were designed for impact test,whose content of steel fibers was 0%, 0.5%, 1.0% and 1.5%, and rubber powder was 0%, 5%, 10% and 15%. The results showed that the compressive strength of concrete decreased with the increase of rubber powder content. When the rubber powder content was costant, the steel fiber content of 0.5% had little effect on the compressive strength and impact toughness of rubber concrete, but it could improve the tensile strength of rubber concrete by 7% to 28%. When the content of steel fiber rubber powder was 1% and the content of rubber powder was 10%, it was the optimal mixing amount of steel-fiber reinforced rubber concrete. The suggested constitutive relation of steel-fiber reinforced rubber concrete was in good agreement with the experimental data.
