The deformation of rubberized concrete under uniaxial compression and three-point flexure is studied in this paper by test, and the load-deflection curves and load-strain curves under three-point flexure are obtained. Three rubberized concrete, with 5%, 10% and 15% rubber contents, were tested. The test results show that rubber powder influences the compressive strength and flexural strength of concrete. The greater of the rubber dosage, the greater of the strength decreasing of concrete. The decline of compressive strength is greater than flexural strength, the ratio of flexural strength to compressive strength of rubberized concrete is 1.08, 1.16, 1.26 times of the normal concrete for three different rubber contents respectively. And the ultimate tensile strain of rubberized concrete is 1.62, 2.25, 2.80 times of the normal concrete respectively. The addition of rubber improved the toughness and deformation ability of the normal concrete.
