三峡水利枢纽工程从二阶段开始进行大规模混凝土施工，混凝土浇筑量达169992万m3，混凝土性能的优劣直接关系到三峡工程质量的好坏。三峡工程所用混凝土集料为斑状花岗岩人工砂、闪云斜长花岗岩人工碎石，采用传统技术方法生产的混凝土，某些技术性能达不到工程要求，导致混 Three Gorges Project from the second phase began large-scale concrete construction, concrete pouring volume of 16999200 m3, the merits of concrete performance is directly related to the quality of the Three Gorges Project is good or bad. Concrete aggregates used in the Three Gorges Project are spotted granite artificial sand and slaked cloud plagioclase granite. The concrete produced by the traditional techniques and methods, some of the technical properties can not meet the engineering requirements, resulting in mixed
