聚羧酸减水剂在水泥自流平砂浆中的应用

Application of the Polycarboxylate Water-reducing Admixture (PCA) in Self-leveling Cement Mortar

对聚羧酸减水剂在水泥自流平砂浆中的应用进行了研究,认为聚羧酸减水剂适用于水泥自流平砂浆并且具有较高的性价比,但在水泥自流平砂浆面层配方设计中应注意气泡问题。

The application of the polycarboxylate water-reducing admixture （PCA） in self-leveling cement mortar was studied. It is thought that the PCA is suitable for being used in self-leveling cement mortar,and the ratio of performance vs. price is higher than that of the original used water-reducing admixtures. But the air bubbles should be considered in the design of formula for self-leveling cement mortar.
