| 摘 要： | 通过试验的方法研究了粉煤灰?硅灰两种活性矿物掺合料对混凝土强度的影响。由试验结果得知:28天龄期时,随粉煤灰掺量的增加,混凝土抗压强度和劈拉强度均下降;随硅灰掺量的增加,混凝土28天抗压和劈拉强度均提高;硅灰与粉煤灰复合的效果要好于单掺粉煤灰或单掺硅灰的效果;随龄期的增加,粉煤灰混凝土的强度逐渐提高,后期强度比纯水泥混凝土强度高。

| Abstract: | Some experimentations were done in order to study the influence of FA and SF to the strength of concrete.In 28 ages,with the quantity of FA increased,the strength of concrete decreases and with the quantity of SF increase,the strength of concrete is enhanced.As age increased,the strength of concrete is on the rise and better than concrete without FA. |
