A study presented findings on the behavior of ordinary concrete against superabsorbent polymers (SAPs) SAPs-modified concrete. Specimens were evaluated for resistance to freeze-thaw, shrinkage, and sulfate attack. Scanning electron microscopy (SEM) was utilized to investigate the modification mechanism. The cement used to prepare concrete samples was No. 42.5 Portland cement. The fine aggregate was a medium-coarse sand with a fineness modulus of 2.7 and a density of 1.57 × 103 kg/m3, in accordance with the specifications of JGJ 52-199. Tap wat...
