WebAlmost all-available research in this area reported that RCA manifest higher water absorption compared to NAs. Many researchers concluded that the porous nature of this residual paste is the main reason behind this behavior [18]. The quantity of water available … WebThe review study yielded the following findings in regards to concrete material properties: (1) replacing NA in concrete with RCA decreases the compressive strength, but yields comparable splitting tensile strength; (2) the modulus of rupture for RCA concrete was slightly less than that of conventional concrete, likely due to the weakened the interfacial …
