| Abstract: | This article chiefly analyses the influence of the biggest grain size and the grain gradation of coarse aggregate on concrete strength and the influence of the surface character, shape of grain and strength on concrete performance is theoretically analyzed. According to the analysis, it is considered that the performances of coarse aggregate, especially the biggest grain size and the grain gradation, have great influence on concrete performance. High-performance concrete has a higher request for all its performances. |
