引用本文摘 要：減水劑是混凝土外加劑中最重要的一個品種。2007年我國合成減水劑產量約284.54萬t，其中普通減水劑占6.2%；高效減水劑占79.3%；高性能減水劑占14.6%。以木質素磺酸鹽減水劑為代表的普通減水劑和以萘系減水劑等為代表的高效減水劑在我國的研究和應用基礎較好，但還可以進行優化改性。而新型多功能聚羧酸系高性能減水劑的開發則是目前研究的熱點，發展迅猛。聚羧酸系高性能減水劑的研究應注重產品系列化，加強分子結構設計，注意原材料和產品分子結構的檢驗和控制，解決好與膠凝材料的適應性問題。 Abstract: The water-reducer is one of most important kinds of chemical adximture for concrete. In China, the out-put of water-reducer, made with synthesis method, is upto 2845.4KT in 2007, among which, the ordinary water-reducer possess 6.2%, the super water-reducer possess 79.3% and the high performance water-reducer possess 14.6%. And in China there is a pretty well foundation on resrarch and application of ordinary water-reducer, which is represented by lignosulfonate, and super water-reducer, which is represented by naphthene sulfonate, etc., but it is still necessary and capable to be improved and modefied. While the research on the new type of high performance water-reducer, the polycarboxylic ester with multi-fuction, is very concerned in the present time and the development is swift and violent. And for research and development of PC water-reducer, it is necessary to attach attention to the product's systemization, to strengthen the design of molecule structure, to pay great attention to inspection and control of raw materials and product's molecule structure, and to solve the problem about compatibility between water-reducer and cementitious material.
