针对低强度自密实混凝土基本力学性能进行了系统的试验研究,利用最小二乘法,分析了低强度自密实混凝土轴心抗压强度、劈裂抗拉强度和弹性模量与立方体抗压强度的相关关系。试验结果表明:与同强度普通混凝土对比,低强度自密实混凝土轴心抗压强度、劈裂抗拉强度和弹性模量偏高。 The basic mechanical properties of low-strength self-compacting concrete were systematically studied. The least square method was used to analyze the compressive strength of low-strength self-compacting concrete with respect to its axial compressive strength, splitting tensile strength and elastic modulus relationship. The test results show that the compressive strength, splitting tensile strength and elastic modulus of low-strength self-compacting concrete are higher than those of ordinary concrete with the same strength.
