摘要
研究了不同掺量、不同细度的几种粉煤灰对水泥凝结时间的影响。结果表明,粉煤灰对水泥凝结时间有很明显的延缓作用,并且其延缓程度随粉煤灰掺量的增加而增大,而粉煤灰的细度对水泥凝结时间的影响不显著。
The effect of several fly ash with different amount and fineness on the setting time of cement is studied. The result show that the fly ash retards the setting time of cement and the retard effect increases as the amount of fly ash does, but the effect of fineness of fly ash on the setting time of cement is small.
