About the research
The main objective of this research was to explore the optimized selection of superabsorbent polymer (SAP) products as internal curing materials in concrete and to examine the effects of the use of eight selected SAPs on properties that affect concrete performance, including shrinkage, hydration, permeability, and strength. Experimental results demonstrated that the use of SAPs improved the shrinkage and hydration of concrete while reducing strength and permeability, although the latter were still within acceptable bounds.
