通过小梁试件三分点加荷试验及棱柱体试件轴心抗压试验,分别测试多孔混凝土的弯拉弹性模量与轴心抗压弹性模量。对试验结果进行回归分析,得出多孔混凝土弯拉弹性模量与弯拉强度、抗压弹性模量与轴心抗压强度之间分别符合相关性良好的幂指数关系,并据此得出多孔混凝土弯拉弹性模量与弯拉强度、抗压弹性模量与轴心抗压强度的对应关系表,作为其弹性模量的推荐值。
The bending elastic modulus and axial compressive elastic modulus of porous concrete were tested respectively by three-point loading test of trabecular specimens and axial compressive test of prismatic specimens. The regression analysis of the test results shows that the flexural modulus, flexural strength, compressive elastic modulus and axial compressive strength of porous concrete accord well with the power index relationship, and the porous Concrete flexural modulus and flexural strength, compressive elastic modulus and axial compressive strength of the corresponding relationship between the table, as the elastic modulus of the recommended value.
