Strength Development and Shrinkage of Superabsorbent Polymer Concrete with Calcium Sulfoaluminate Clinker and Shrinkage Reducing Admixture

In this study, we analyzed the strength and shrinkage properties of concrete with three additives, superabsorbent polymer (SAP), calcium sulfoaluminate (CSA) clinker, shrinkage-reducing admixture (SRA), to verify internal curing reduction effects. According compressive tests, use SAP as an additive resulted in a slight decrease strength, whereas using 10% CSA clinker 8 MPa higher than that ordinary concrete. observed behavior at surface middle while exposing ambient air for 80 days. results, SRA had greater effects on clinker. particular, rate achieved by adding mixture was approximately 32% compared Based result, concluded reduced due effect (humidity adjustment within concrete) SAP. addition, maximized when added these materials simultaneously. together found be 69% When CSA, SAP, mixture, 96% concrete, making best achieved.
