摘　　要：通过轻骨料混凝土在不同塑钢纤维掺量下的抗压强度、劈裂抗拉强度、抗折强度、弯曲韧性和抗冲击性能的试验研究,分析塑钢纤维掺量对轻骨料混凝土力学性能的影响。结果表明:在轻骨料混凝土中掺入塑钢纤维对其抗压强度、抗折强度没有明显影响,但其弯曲剩余强度显著提高,劈裂抗拉性能和抗冲击性能得到明显改善。Lightweight aggregate concrete （LWAC） specimens with different plastics-steel fiber volumes were tested in this study to evaluate the effects of plastics-steel fiber fraction on the mechanical properties of LWAC. The experimental results indicated that incorporation of steel fiber into LWAC can greatly improve mechanical properties like flexural toughness and impact resist-ance, but it has little effect on compressive strength and flexural strength.
