养生龄期对二灰配合比—强度关系的影响

The affect of lime-fly ash proportion intensity by maintenance period

二灰的强度随配合比而变,但在不同龄期,配合比与强度之间的关系不尽相同,根据实验结果,得到各个龄期时二灰的配合比—强度关系曲线,结果表明,这些曲线走势不完全一致,并且提出以二灰早期的强度来确定其最佳配合比欠佳。

The intensity of lime-fly ash varies with the proportion between lime and fly. But in different period, proportion-intensity is also different. The chart of proportion-intensity in every period can be acquired by experiments, but the direction of these charts doesn＇ t agree with each other. At the same time, confirming the better proportion of lime-fly ash only by the intensity that is in the early period isn＇t very fit.
