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。
The research on the effcct 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.
