混凝土减水剂的研究进展与发展趋势

Research Progress and Development Trend of Concrete Water Reducer

减水剂是混凝土中添加的一种外加剂,它能够使混凝土预拌物的和易性及工作性能得到改善,同时又能够降低用水量,使混凝土预拌物具有较好的和易性,进而达到提高混凝土强度的目的。本文从减水剂发展概况、分类及性能等方面对混凝土减水剂作出系统的阐述。

Water reducer is a kind of admixture added in concrete.It can improve the workability and working performance of concrete ready-mixed materials.At the same time,it can reduce the water consumption and make the concrete ready-mixed materials have better workability,so as to improve the strength of concrete.The development,classification and performance of concrete water reducer are expounded in this paper.
