摘要：
Polymers have been used in cement-based materials to modify important characteristics and properties such as rheology, water-retention ability, cohesion, adhesion, and toughness of fresh and hardened mortars, as well as concretes. In this paper, the characteristic properties of ordinary portland cement (OPC) hydration in the presence of fly ash (FA) and polyvinyl alcohol (PVA) have been studied. The setting times of OPC are prolonged when FA and PVA are added separately or in combination. The compressive strength of FA-blended cement in the presence of PVA at 28 days of hydration is enhanced considerably. An interaction between PVA and hydrating blending cement is expected. Based on the results, the mechanism of action of PVA on the hydration of FA-blended cement is discussed.
