| 摘 要： | 减缩剂是一种可显著降低水泥基材料收缩的新型化学外加剂,现有研究主要集中在其对水泥基材料宏观性能的影响等方面,而对减缩剂在胶凝材料-水界面的吸附特性鲜有报道,减缩剂在水泥基材料中的存在状态还未被完全认知.以两种类型的聚羧酸减水剂作为对比,对两种减缩剂在水泥、矿渣及粉煤灰颗粒上的吸附进行研究.结果显示减缩剂和减水剂在固体颗...

| Abstract: | Shrinkage reducing admixture(SRA) is a novel chemical admixture which can significantly reduce the shrinkage of cement based materials.Most of researches mainly focused on the effect of SRA on macroscopic properties of cement based materials.There are,however,few reports on the adsorption of SRA on interface of cementitious materials-water.Thus,the existential state of SRA in cementitious materials is not well understood.In this study,the adsorptions of two SRA products on solid particle surface of cement,b... |
