EPP load-bearing insulation concrete is prepared by adding EPP particles into the cement mortar matrix.In order to study the deformation performance of three kinds of EPP load-bearing concrete with different strength grades, the axial compression test of EPP load-bearing concrete is carried out.The experimental results show that the elastic modulus and poisson's ratio decrease with the decrease of compressive strength, but the plasticity increases gradually.The experimental value of elastic modulus is higher than that of empirical formula, and according to the empirical formula of elastic modulus, the formula of elastic modulus of EPP load-bearing insulation concrete is obtained.
