在工程应用中,聚羧酸系外加剂对混凝土原材料的敏感度比传统萘系外加剂更高。本文阐述了如何通过复配一些增稠及保水等组分,尽可能的降低聚羧酸系外加剂对混凝土敏感度的问题,以提高聚羧酸系外加剂在商品混凝土应用中的工作性能。
In engineering applications, polycarboxylate admixtures are more susceptible to concrete raw materials than conventional naphthalene admixtures. This article explains how to reduce the sensitivity of polycarboxylate additives to concrete as much as possible by compounding some components such as thickening and water retention so as to improve the performance of polycarboxylate additives in commercial concrete applications.
