A new multiphase material composite concrete is prepared by adopting artificial expanded perlite as coarse aggregate and mixing into it the randomly distributed steel fibers simultaneously. Strength and deformation as mechanical performance of this new concrete material are studied by the tests of cube compressive strength, split and tensile strength, buckling strength, axis compressive strength, and modulas of elasticity. Strength and deformation as mechanical performance of concrete improved significantly after adopting light aggregate and adding steel fibres, as shown by results of tests.
