Micro-electrophoresis is used to measure the Zeta-potential of three kinds of hydrated calciumsilicates in different crystallinities and some influence factors on Zeta-potential are studied.Theresulss show that the sign and the value of Zeta-potential depend on not only the surface charac-teristics,but also the concentration and type of ion in the medium solution and the kinetics factionsrelated to the measure condition as well.In this paper,the tentative models of electrical double-lay-er structure of different kinds of hydrated calcium silicates in different medium solution are given.
