Abstract

the cube compressive strength splitting tensile strength and flexural strength of C30-level recycled concrete were tested, which was based on the testes of natural concrete. The kinds of recycled aggregates’ service lives were 0 year, 10 years and 40 years, and the substitution rates were 30%, 50%, 70% and 100%. The experimental results indicate that the fracture morphology and process of the cube compressive strength splitting tensile strength and flexural strength of the recycled concrete are consistent with the ones of the natural concrete. In the case of the same water-cement ratio, the cube compressive strength of recycled concrete is higher than the ordinary one, and the splitting tensile strength is lower than the ordinary one. The flexural strength of the recycled concrete is higher than the ordinary one, the one of the substitution rate of 50% is lower than ordinary one; In addition, it indicates that the concrete strength will be influenced by the life of recycled coarse aggregate.
