摘要：
This study investigates the behavior of concrete with superabsorbent polymer (SAP) under freezing conditions. SAP particles absorb water and create air voids in hardened concrete upon releasing the absorbed water. The air voids are posited to improve the freeze resistance of concrete. While this phenomenon has been experimentally verified, a contradictory finding has also been reported. This study elucidates the conflicting observations by interpreting the water reabsorption behavior of SAPs in hardened concrete. Previous models have been modified considering the SAP characteristics in hardened concrete. Lastly, the optimal SAP content for enhanced freeze resistance are proposed.
