Abstract In this study, the strength and the carbonation speed of the mortar incorporating recycled fine aggregate were examined. Strength and carbonation speed could be evaluated by total water-cement ratio, ...which was obtained by summation of water content and total water absorbed in aggregate. Pore volume between 50nm and 2μm in new cement matrix phase was porous and loose when recycled fine aggregate with high water absorption was used in mortar. Performance of mortar incorporating recycled fine aggregate correlated closely with pore volume between 50nm and 2μm in new cement matrix phase. It was suggested that water included in recycled aggregate moved to new cement matrix phase during cement hydration.show more
