对同一混凝土配合比,不同形状和不同掺入量的稻草纤维混凝土进行了物理力学性能试验。结果表明,同一混凝土配合比下,随着稻草纤维掺量的增加,不同形状稻草纤维混凝土的物理力学性能会有所影响,抗压、劈裂抗拉及抗折强度会有所降低,但稻草纤维的掺入不仅能改善混凝土的韧性,也可提高混凝土的抗冲击性能。 The physical and mechanical properties of straw fiber reinforced concrete with the same concrete mix ratio, different shapes and different dosages were tested. The results show that the physical and mechanical properties of different shapes of straw fiber reinforced concrete will be affected with the increase of straw fiber content at the same concrete mix ratio, and the compressive strength, splitting tensile strength and flexural strength will be reduced, but straw Fiber incorporation can not only improve the toughness of concrete, but also improve the impact resistance of concrete.
