An indicator named as water absorption ratio of super-absorbent polymer (SAP) was proposed. The effect of SAP water absorption ratio on the absorption kinetics of SAP in centrifugal liquid from cement slurry (CLCS), rheological property of fresh concrete with internal curing, compressive strength and shrinkage of hardened concrete with internal curing was investigated. The results indicate that the absorption of SAP in CLCS exhibits a law of rapid increase, gradual decrease and final stability. The peak value of absorption and the release time increase, the yield stress of fresh concrete gradually increases and the plastic viscosity gradually decreases as the SAP water absorption ratio increases. SAP reduces the early strength and shrinkage of concrete significantly, and has little impact on the long-term strength. SAP also has no impact on the compressive strength and shrinkage of hardened concrete evolved with curing time when the water absorption ratio is 1.94-6.16.
