摘要
石膏是使用非常广泛的建筑材料,但耐水性差的特性制约着其实际应用。分析了石膏制品的吸水性原理,包括二水石膏的晶体结构和水化机理;从二水石膏溶解度、试块微孔性和毛细现象3方面解释了石膏制品耐水性差的原因,并总结了当前国内外石膏制品的主要防水处理措施。
Gypsum is very widely used in building materials, but its poor water-resistance feature restricts the practical application. This paper analyzes the hygroscopicity principle,including the crystal structure and hy- dration mechanism of dihydrate gypsum,and explains the reasons of poor water-resistance of gypsum through the solubility,microporosity and capillarity,sums up some current major waterproofing measures at home and abroad.
