Deterioration mechanism understanding of recycled powder concrete under coupled sulfate attack and freeze–thaw cycles
Construction and Building Materials(2023)
摘要
•The deterioration of RPC after sulfate freeze–thaw cycles under different replacement rates and mass proportion were studied.•The increase in RP replacement rate led to a decrease in the attack resistance of RPC.•The RPC partition-interface model and RPC damage model was established.
