Abstract：In this paper,the effects of silica fume content and age on the compressive strength of high performance self-com-pacting concrete(HPSCC)were investigated through two-factor variance analysis,and a compressive strength prediction model was es-tablished.Studies have shown that both the silica fume content and age have a significant effect on the compressive strength of HP-SCC.The compressive strength of the cube first increases then decreases with the increase of silica fume content and then,the 28 d compressive strength reaches the maximum value when the silica fume content is 13%.The increase of silica fume content has a certain effect on change of early compressive strength,and the 7 d/28 d strength ratio reaches 92.1%when the content is 15%.The HPSCC compressive strength prediction model based on silica fume content and age has been established.
