Wang Wei;Zhang Zuowang;Gao Jianyang;Fu Dong;Henan Haihua Engineering Construction Management Co., Ltd.;Henan WuJian Concrete Co., Ltd.;  
In this paper, the production technology of "secondary feeding" is studied, and the optimum ratio of two feeding times is determined. The workability and mechanical properties of C30 concrete produced by "secondary feeding" and "primary feeding" are compared, and the economic benefits are analyzed. The results showed that using "secondary feeding" method can raise concrete workability and mechanical properties, and get remarkable economic benefits.
