Abstract

Taking account of concrete cube strength and coarse aggregate replacement rate,tensile strength and shear strength property of recycled aggregate concrete had researched.In this paper,the tensile samples were standard cube,bending strength test used non-standard samples,section of the shear test beams was uniform depth and varying width.The stress strength and the strain of the test samples were researched.The following results were obtained: 1) the split strength of recycled concrete was lower than the natural aggregate concrete;2) bending strength of recycled concrete had a large range discrete,a reasonable regression formula could not be found;3) the ultimate shear stress was not changed with the replacement variation,regression of the shear strength and the cube strength had a lower relationship coefficient;4) the shear stress-principal strain curve of sample beams was a line when the indicated value was less than about 70% maximum value,the measured nominal stress of shear and shear modulus of elasticity were lower than natural coarse concrete.
