摘要：研究了塑钢纤维掺量（0.7%、1.0%、1.3%、1.6%、1.9%）对核桃壳轻骨料混凝土性能的影响。结果表明：掺入塑钢纤维后，核桃壳轻骨料混凝土的相对坍落度下降，抗压强度略有提升，劈裂抗拉强度和抗冲击韧性显著提高，透水孔隙率和含气量增大；当塑钢纤维掺量为1.3%时，核桃壳轻骨料混凝土的28 d抗压、劈裂抗拉强度最高，分别为45.2 MPa、3.82 MPa。 Abstract: The influence of the content of plastic steel fiber (0.7%, 1.0%, 1.3%, 1.6%, 1.9%) on the properties of walnut shell lightweight aggregate concrete was studied. The results show that after adding plastic steel fiber, the relative slump of walnut shell lightweight aggregate concrete decreases, the compressive strength increases slightly, the splitting tensile strength and impact toughness increase significantly, and the permeable porosity and air content increase. When the content of plastic steel fiber is 1.3%, the 28 d compressive strength and splitting tensile strength of walnut shell lightweight aggregate concrete are the highest, which are 45.2 MPa and 3.82 MPa respectively.

Abstract: The influence of the content of plastic steel fiber (0.7%, 1.0%, 1.3%, 1.6%, 1.9%) on the properties of walnut shell lightweight aggregate concrete was studied. The results show that after adding plastic steel fiber, the relative slump of walnut shell lightweight aggregate concrete decreases, the compressive strength increases slightly, the splitting tensile strength and impact toughness increase significantly, and the permeable porosity and air content increase. When the content of plastic steel fiber is 1.3%, the 28 d compressive strength and splitting tensile strength of walnut shell lightweight aggregate concrete are the highest, which are 45.2 MPa and 3.82 MPa respectively.
