| 要旨 | It has been noticed that the mixtures with superabsorbent polymer (SAP) frequently exhibit an expansion at early ages. In this study, the expansion in mixtures with SAP was investigated in relation to the hydration process of cement at early age. It is suggested that the internal water released from SAP may contribute to increase the expansion and that SAP may affect the evolution of microstructure even before the initial setting time. Differences in the subsequent expansive behaviors are related to the initial distribution of water released from SAP. |
