聚丙烯酰胺──铝酸一钙水化过程的一些特性分析

Some Characteristic Analyses in the Hydration System of Polyacrylamide-monocalcium Aluminate

本文研究了聚丙烯酰胺与铝酸一钙水化过程中的液相离子浓度、水化热的变化规律，对反应体系的物相变化进行了ＸＲＤ分析，比较了掺入与不掺聚合物两种反应体系的差别，讨论了水化过程的特点，为聚合物与水泥间的反应机理提供了直接的实验证据。

The development regularity of ionic concentration and hydration heat inthe hydration system of polyacrylamide and monocalucium aluminate have been studied,and the reaction products were analyszed by XRD. Two kinds of the different hydrationcharacteristic were discussed and the res.ults gave the direct proof for the reaction mechanism between polymer and cement.
