Abstract: The characteristic of single stain aggregate not llne form is studied on a new angle by certain measurement method And the concrete engineering applying which cant satisfy the request of the possible use of the gather aggergate is explored Then the method of controlling the productive quality ofthe aggregate is put forward．

Key words: shape characteristic, wealthy deal of sanded grout, even degree coeficient

摘要： 采用一定的测定方法，从新的角度对单一粒径状态下集料非线形特征进行研究，探索在砼工程中应用不能满 足要求集料的使用可能性，以及控制集料生产质量的方法．
