Abstract: In order to conduct experimental research on the basic mechanical properties of waste ceramic aggregate concrete, C30 concrete was used as a benchmark to prepare recycled aggregate concrete by using waste ceramic to replace natural stones with five replacement rates of 20%, 35%, 50%, 65% and 100%.And the mechanical properties of the recycled aggregate concrete were tested.The addition of mineral admixtures, fibers and changing the particle size gradation of coarse aggregates were applied to enhance strength and toughness of the waste ceramic aggregate concrete.The results show that the compressive strength, splitting tensile strength, flexural strength, axial compressive strength and elastic modulus of the waste ceramic aggregate concrete specimens decrease with the increase of the waste ceramic aggregate substitution rate.When the replacement rate of waste ceramic aggregate does not exceed 50%, the mechanical properties of recycled aggregate concrete specimens reduce a small extent, but the decrease becomes very obvious when the substitution rate exceeds 50%.The results of orthogonal design tests of three factors and three levels show that the optimal combination of concrete mechanical strengthening and toughening is that the volume of basalt fiber is 0.15%, the silica fume is 15%, the mass ratio of different particle size range of coarse aggregate of 10~20 mm and 5~10 mm is 5:2.
