Thermal and mechanical performance of geopolymer concrete with recycled aggregate and copper slag as fine aggregate

Abstract This study investigates the thermal and mechanical performance of geopolymer concrete incorporating recycled coarse aggregate (RCA) and copper slag (CS) as sustainable alternatives to natural aggregates. The geopolymer binder comprises fly ash (FA) and ground granulated blast furnace slag (...
