摘要
利用聚乙烯醇(PVA)改善土聚水泥的强度性能,并通过XRD、SEM现代测试方法进进行了机理分析。实验结果表明,PVA促进土聚水泥水化反应的进行,改变水化产物的生成部位和形貌,使硬化水泥浆体更加密实,从而提高土聚水泥强度。
Strength properties of geopolymenr cement are improved by polyvinyl alcohol. The mechanism is analyzed through XRD,SEM. The experimenta/results show that PVA accelerates the hydration of geopolymer cement, varies the morpha and forming position of hydration products and makes the hardened paste denser. As a result the strength properties of geopolymer cement are improved.
