主　　题：C&D waste recycled insulation concrete blocks experimental performance 

摘      要：Construction and demolition(C&D)waste has seriously affected the ecological *** 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 *** 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 *** experimental research and performance test analysis,the best mix ratio of the product and the mechanism of each additive were *** 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.
