以不掺塑钢纤维的LC30轻骨料混凝土为基准,通过塑钢纤维轻骨料混凝土的抗压、劈裂抗拉、抗折、弯曲韧性、抗冲击试验,研究了塑钢纤维掺量对轻骨料混凝土力学性能的影响。研究结果表明:塑钢纤维对轻骨料混凝土抗压性能改善效果不明显,但能够显著提高轻骨料混凝土的劈裂抗拉强度、抗折强度、弯曲韧性及抗冲击性能。
Based on the LC30 lightweight aggregate concrete with no steel fiber added, the effects of steel fiber content on the properties of lightweight aggregate were studied by compressive strength, splitting tensile strength, flexural strength, flexural toughness and impact resistance of steel fiber reinforced lightweight aggregate concrete. Influence of Mechanical Properties of Concrete. The results show that the plastic fiber has little effect on the compressive properties of lightweight aggregate concrete, but can significantly improve the splitting tensile strength, flexural strength, flexural toughness and impact resistance of lightweight aggregate concrete.
