This paper compares two different sources of internal water supply in curing: the replacement of a portion of the sand by partially saturated lightweight fine aggregate; and the addition of superabsorbent polymer particles (SAP). The results clearly demonstrate that autogenous shrinkage can be reduced by internal curing. Autogenous shrinkage is reduced due to larger …
