摘　　要：研究了不同C3S含量的阿利特-硫铝酸盐水泥熟料与粉煤灰混合材的适应性。结果表明:C3S含量一定时,随粉煤灰掺量增加,水泥的凝结时间延长,抗压强度降低;粉煤灰掺量一定时,随C3S含量的增加,水泥的凝结时间延长,抗压强度增大;C3S含量增大时,随着粉煤灰掺量增多,水泥各龄期抗压强度降幅减小;掺加粉煤灰后水泥的早期抗压强度降低幅度较大,后期抗压强度降幅较小。熟料中C3S含量低时,对高粉煤灰掺量的适应性差;C3S含量高时,其适应性好。The adaptability between alite-sulphoaluminate cement clinkers with different amount of C3S and fly ash were studied.The results showed that the setting time of the cement delayed and the compressive strength of cement decreased with increasing of fly ash amount with a fixed C3S content￡？ the setting time of cement with a fixed content of fly ash delayed and the compressive strength of cement increased with the increasing of C3S content,and compared to the original cement,when the C3S content increased the strength loss at each age was lower with the increasing of fly ash content.With the addition of fly ash,the decreasing range of early compressive strength was remarkable,but the loss of later compressive strength was insignificant.The clinker with higher C3S content showed better adaptability with high addition ratio of fly ash.
