摘　　要：Construction and demolition(C&D)waste has seriously affected the ecological environment.The utilization of C&D waste resources can greatly alleviate this problem,and it is an important way to help achieve the goal of zero carbon in 2050.In this study,insulation concrete blocks were developed with recycled aggregates,cement,fly ash as main raw materials,expanded polystyrene(EPS)insulation boards as block insulation filling material,and selfdeveloped construction waste composite activator,interface enhancer,surface modifier and other additives.Through experimental research and performance test analysis,the best mix ratio of the product and the mechanism of each additive were proved.The experimental results showed that the insulation concrete block prepared under the conditions of recycled aggregates sand ratio of 45%,active activator Na_(2)SO_(4)content of 0.15%and fly ash content of 30%has the best performance and meets the relevant standards.
