| Abstract: | In this paper, high performance concrete with silica fume and fly ash added is made. The effect of related factors to 7 days, 28 days and 90 days compressive strength have been studied by the method of orthogonal experiment, and the optimized mix ratio of high performance concrete has been determined. The thesis presents several linear regression equations that of the content silica fume, fly ash and the ratio of w/b with compressive strength. |
