Experimental study on the influence of recycled aggregate substitution rate on the mechanical properties of recycled aggregate concrete under sulfate erosion conditions

Abstract To investigate the degradation of recycled aggregate concrete (RAC) under sulfate attack, four groups of RAC cubic specimens (168 in total) were prepared. The influence of recycled coarse aggregate (RA) replacement ratio on the mechanical properties of RAC under sulfate exposure was analyze...
