摘要
高性能胶凝材料主要用于高性能混凝土，具有强度高、需水量小、水化垫低和收缩小等特点。按掺高效减水剂的胶凝材料的流变性能来优化石膏的掺量是高性能胶凝材料的特有技术之一。试验研究了石膏的掺量对高性能胶凝材料的需水量、凝结时间、强度、收缩性的影响，以此作为优化石膏掺量的依据。
High Performance cementitious material is specially used for high Performance concrete. Propetties of that are high strength, low water demand, low hydration heat and low shrinkage. OPtimization of gypsum content according to rheology of cementitious material with superplasticizer is one of technology peculiarities of high performance cementitious material. The influence of gypsum content on water demand, time of setting, strength and shrinkage of high Performance cementitious material is tested as warrant for optimizing gypsum content.
