摘要
从抗压强度、结合水含量、粉煤灰反应程度、水化样孔溶液碱度等方面研究了 0. 3水灰比和 0. 5水灰比系列的粉煤灰—水泥混合体系水化特性。研究结果表明,水灰比为 0. 3时,粉煤灰掺量不宜超过 30%,早期 0. 5水灰比强度不及 0. 3水灰比。0. 3和 0. 5水灰比系列中,粉煤灰在 28天前几乎不会与CH发生火山灰反应。
The hydration processes of fly ash cement paste were investigated by examination the compressives strength, the non-evaporable water content, the fraction of reacted fly ash,and the PH of pore solution, It was shown from results that at the low w/c ratio the compressive strensth was greater than the high W/C ratio at early ages, and fly ash didn＇t have hydration reaction.
