| 摘 要： | 混凝土掺加粉煤灰,可以起到改善混凝土性质,节约水泥的作用。但掺入后混凝土早期强度或多或少地要受到一些影响。制约混凝土早期强度的主要因素是水灰比,为使混凝土掺加粉煤灰其强度不受影响,依国内外资料对粉煤灰混凝土进行探讨,并提出了计算公式。

| Abstract: | If concrete mixed with fly ash , its some characteristics will be improved and cement will be saved. But its early strength may be influenced more or less. The water ratio is a main factor that influences the early strength of concrete.In this paper, a concrete mixed with fly ash is discussed and a formulation is given acceding to some Chinese and foreign materials for reason given above mentioned. |

| Keywords: | fly ash concrete water ratio compreessive strength mixing proportion |
