✦ Synopsis

Zeta-potential measurements provide new informations on cement hydration, gel structure formation and the effects of chemical admixtures. The formation and significance of a zeta-potential of cement in aqueous suspension is discussed with respect to the hydration of cement and some new data on the zeta-potential of cement and fly ash under various conditions are presented.

The theory of the non-equilibrium double layer is applied to the interface between an oxidic material and an aqueous electrolyte. It is shown, that the theory also applies, when slow chemical reactions occur at the solidliquid interface. The theory is applied to cement and the results are compared t
