【摘要】 研究了纤维对轻集料混凝土的抗冲击韧性的影响。试验分别测试了纤维单掺、纤维混掺及层布式钢纤维轻集料混凝土的抗冲击能量。试验结果表明:纤维的掺入提高了轻集料混凝土的抗冲击能量,其中以钢纤维的效果最为明显,混掺纤维次之;当钢纤维掺量为2%,其抗冲击能量值为素混凝土的3.16倍。更多还原

【Abstract】 The research on the effect of fibre on impact resistance of lightweight aggregate concrete(LWC) was studied.The energy of impact resistance of LWC with single fibre、composite fibres and top-to-bottom steel fibre were tested respectively.Results show that:the impact energy of LWC increased remarkably as a result of using fibre,especially steel fibre.更多还原
