摘　　要：采用湿度可控的液态簧振动力学谱方法,对酒石酸掺入量分别为1.2 wt%、1.5 wt%的水泥复合体系进行了实时检测,结果表明:酒石酸主要对水泥水化反应的起始期产生作用(过程ii),而对其他过程的作用影响不大.当酒石酸掺入量为1.2 wt%时,过程ii出现了3个子过程;而酒石酸掺入量为1.5 wt%时,过程ii出现了2个子过程.由于酒石酸的掺入,对水泥浆体中Ca(OH)_2的浓度起到了一定的调控作用,延长了过程ii的反应时间,使得C3S水化更加充分.而对水泥水化反应过程ii以及水化反应进入稳定期的时间点进行统计,也从侧面证实了这一点,表明酒石酸是一种主要在水泥水化反应起始期起作用的缓凝剂.In this paper, RMS-L method was used to detect the cement composite system with 1.2 wt% and 1.5 wt% tartaric acid admixture respectively. The results show： Tartaric acid has a major effect on the initiation of ce- process-ii has two sub-processes. In this paper, the concentration of Ca（OH）2 in cement paste was regulated by tar- taric acid, and the reaction time of process ii was prolonged, which made C3S hydrate more fully. The time required for the hydration reaction process -ii and the reaction into the stabilization period is also confirmed, and this is con- firmed from the side, indicating that tartaric acid is a retarder dration reaction. that works primarily at the beginning of the cement hy-dration reaction.
