The result showed that the one-valence cationsaccelerate the hydration process of α-hemihydrate gypsum greatly because they improvethe dispersed degree of α-hemihydrate gypsum particles due to the remarkable effect ofincreasing theζpotential; the effects of bivalent and trivalent cations on ζpotentialdecrease in turn, compared with monovalent cations, the effects on both the disperseddegree of α-hemihydrate gypsum particles and the setting time of paste are little.
研究还表明：由于一价阳离子能较大程度地提高石膏浆体的ζ电位，因而有效地提高了石膏颗粒的分散程度，对α半水石膏的水化加速作用很大，而二、三价离子对石膏浆体的ζ电位影响依次减小，对半水石膏颗粒的分散程度和浆体凝结时间的影响均不如一价阳离子作用大。
