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。
Based on the experimental study of compressive strength, splitting tensile strength, flexural strength, flexural toughness and impact resistance of lightweight aggregate concrete with different steel fiber content, the effects of plastic fiber content on the mechanical properties of lightweight aggregate concrete influences. The results show that the incorporation of plastic fiber into lightweight aggregate concrete has no obvious effect on the compressive strength and flexural strength, but the flexural residual strength is significantly increased. The tensile splitting tensile strength and impact resistance are obviously improved.
