摘　　要：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-intensity self-compacting concrete are systematically studied.The correlativity among the axial compressive strength, splitting tensile strength and elastic modulus of low-intensity self-compacting concrete and cube compressive strength of low-in- tensity self-compacting concrete are analyzed through the least square method.The experimental results show,with the same strength of ordinary con- crete contrast, the axial compressive strength, splitting tensile strength and elasticity modulus of low-intensity self-compacting concrete are high.
