摘要
基于对泡沫混凝土材料性能及其影响因素的研究,采用普通硅酸盐水泥制备泡沫混凝土棱柱体试件,进行单轴受压试验,分析试件的破坏形态及其力学性能;分别拟合密度800,1000,1200,1600(kg/m^3)的泡沫混凝土单轴受压应力-应变曲线,并将上述4条曲线拟合为泡沫混凝土单轴受压应力-应变全曲线,确定其本构方程,为有限元分析和计算提供依据。
Based on the study of material properties of foam concrete and its influencing factors, a uniaxial compression test on the foam concrete prism blocks is carried out. The failure modes of the block and the mechanical properties are analyzed. The blocks have densities of 800, 1000, 1200, 1600（kg/m3）, and stress-strain curves of 4 kinds of foam concrete are fitted respectively. Then the stress- strain curve and its constitutive equation of foam concrete under uniaxial compression are determined by four curves, can provide the basis for the finite element analysis and calculation.
