摘要
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。
LC30 LWAC without adding plastic steel fiber is used as a benchmark of concrete. Through the experiments research on the compressive properties, splitting tensile properties, flexural properties, flexural toughness and impact properties,the effects of mixing amount of fibers on the mechanical properties of concrete are studied. The results show that plastic steel fiber has no much influence on the compressive strength but can significantly improve the splitting tensile strength,flexural strength,impact resistance and toughness.
