粉煤灰对高性能混凝土强度和电通量的影响

摘要

According to the experiments on fly ash of various mixing amount to replace the cementing materials in concrete, the paper indicates the strength of 7 d, 28 d and 56 d discloses the time quantum of the fly ash＇ s active effect and the optimal mixing amount of the fly ash in the maximal value of the 56 d strength, and the optimal mixing amount of the fly ash with the minimum 56 d electric flux, so as to provide the refer- ence for the mixing proportion of the high-performance concrete.%通过混凝土中不同掺量粉煤灰取代胶凝材料的试验，7d，28d和56d的强度表明了粉煤灰活性效应的时间段，以及56d强度最大值时的粉煤灰最佳掺量；56d电通量最小值时粉煤灰的最佳掺量，为高性能混凝土配合比的选配提供了试验依据。
