摘　　要：石膏是国际上推崇使用的绿色建材。我国是石膏资源大国 ,具备发展石膏建材的资源和政策优势。使用外加剂是提升石膏基材料技术经济水平 ,推动石膏行业科技进步的最有效途径 ,也是高性能石膏基材料的核心技术。本文综述了国内外建筑石膏减水剂、缓凝剂、保水剂研究的现状 ,并对国内石膏外加剂研究与应用中存在的问题进行了分析。Gypsum is a green building material popular all over the world. Our country has abundant gypsum resource. Adding admixtures is one of most efficient ways to improve technological and economical level,and promote scientific progress of gypsum industry. It is also the core technology of high performance gypsum-based materials. In this paper,the status and development tendency of research on building gypsum admixtures such as water-reducing agents,retardants,and water-retention agents both at home and abroad are reviewed.Some problems existing in research and application of admixtures for gypsum have been put forward.
