An investigation into the interaction between alkaline cations and calcium silicate hydrates (CSH) was conducted by electrokinetic measurements, which provided information on the nature of the interface between the solid and its equilibrium solution. Calcium constitutes for the CSH surface a potential-determining cation. A model of the CSH surface could be proposed, accounting for the experimental evolution of the CSH zeta potential. The necessity of studying the zeta-potential evolution of the system as a function of the calcium activity, instead of its concentration, was underlined. The results obtained suggest a specific interaction between cesium and the CSH surface, whereas sodium and lithium may behave as indifferent cations toward the interface.
