摘　　要：研究了硅粉对混凝土抗折强度的影响，根据试验数据总结出混凝土２８ ｄ 抗折强度与灰水比、硅粉掺量之间的定量关系；研究了硅粉和粉煤灰的复合效应，总结出水灰比为０－４５ 的情况下，混凝土２８ ｄ抗折强度随粉煤灰掺量和硅粉掺量的变化规律；并对粉煤灰混凝土的后期抗折强度进行了研究。The effect of silica fume on the bending strength of concrete was studied.According to the data obtained,the quantitative relationship between the 28day bending strength of concrete and water binder ratio as well as the adding quantity of silica fume was summarized.The composite effect of silica fume and fly ash on concrete was studied.The quantitative relationship between the 28day bending strength of concrete and the adding quantity of fly ash as well as silica fume was summarized( W/C is 0 45).The late bending strength of fly ash concrete was also studied.
