Abstract：
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.
