摘要:

可再分散乳胶粉是制备新型水泥砂浆的一种非常重要的聚合物添加剂,常用来赋予水泥砂浆特殊的功能。介绍了可再分散乳胶粉对水泥砂浆工作性能、力学性能、耐久性能等3个方面的影响,及相应的基于聚合物膜结构和水泥砂浆的微观结构演变分析的作用机理,并对未来研究方向提出了建议。

The redispersible polymer powder is a polymer additive in novel cement mortars with some special functions. The effect of redispersible polymer powder on the properties of cement mortars (i.e., workability, mechanical properties and durability) was investigated. The mechanism of modification was analyzed according to the distributions of latex film structure and evolution of microstructure in cement mortars. In addition, the further development of this aspect was also proposed.
