| Abstract: | This paper presents the experimental results of a study on the effect of sand on the workability of C50 high performance concrete by the three factor of sand fineness modulus, clay content and the lump of clay content, through investigating the C50 high-performance concrete used for precast box girder. The optimization range of the guide line is obtained. All the results provide a reference for the practice and work in construction. |
