Abstract

This paper examines the effect of superabsorbent polymers (SAPs) with varied particle sizes and contents on the mechanical strength and shrinkage of cement concretes. SEM measurements were performed to identify the mechanisms of internal curing. It was shown that the incorporation of SAPs generally increased the compressive strength and shrinkage resistance capability of specimens, especially the relatively small particle sizes. A large number of hydration products were generated and grouped around the remained pores of SAP, which could enhance the hydration degree and improve the compactness of cement concretes, as well as the performance growth.
