| 要旨 | Superabsorbent polymers (SAP) are hydrogels capable of absorbing water, and expected to apply widely to concrete as additives. This study addresses the kinetics of water uptake and release of SAP and the rheologial behavior of fresh cement pastes with SAP. It is suggested that similar variation tendency of absorption capacities of SAP could be obtained by the two measurement techniques. The greater the kinetics of the liquid uptake, the rapider the kinetics of the liquid release. The addition of SAP affects the plastic viscosity, due to supplement of water to alleviate internal friction. |
