引言骨料是普通混凝土组成中比重最大的材料。长期以来,人们普遍将它当作惰性填充料,认为它的主要功能是节约水泥用量。其实骨料在混凝土中所起的作用不亚于水泥胶结料,尤其是在混凝土结构形成及使用过 Introduction The aggregate is the material with the highest specific gravity in the ordinary concrete composition. For a long time, people generally regard it as an inert filler, thinking that its main function is to save cement consumption. In fact, aggregate plays a role in concrete as much as cement binder, especially in the formation and use of concrete structures.
