高性能胶凝材料的研究综述

混凝土的高性能化对胶凝材料提出了高性能化的要求.针对目前混凝土掺合料、外加剂的使用情况及所存在的问题,通过国内外大量文献的研究、分析,对高性能胶凝材料进行了研究,提出了高性能混凝土用胶凝材料的发展方向,总结出一种适于生产环保型高性能胶凝材料的复合分磨-混磨生产体系.结果表明:用该体系生产的高性能胶凝材料可直接配制高强高性能混凝土,大大提高了工业废渣的利用率,简化了混凝土的配制、生产方法.

Study on high performance of cementitious material

Requirement for high performance of cementations material was put forward with the development of high performance concrete.According to service condition and existing question of concrete blends and additives at present,high performance cementitious material was studied by research and analysis on national and foreign documents in the paper.At the same time,the development direction of cementitious material in high performance concrete was put forward,and a composite separate grinding-mix grinding system applied to produce environmental protection high performance cementitious material was generalized.The preliminary results indicate that high performance cementitious material produced by this system may directly prepare high strength?high performance concrete,which greatly increase usage of industrial residue and simplify preparation and production process of concrete.
