The Zeta-potential of different types of cement and fly ashes has been measured under various conditions of pH and ionic strength.The results obtained are in full agreement with the modified Stern-Grahame-model of the reactive double layer on cement. The data further indicate that Na + and K + are p

✦ Synopsis
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 to equilibrium models.

Two series of pastes were prepared having a water to solids ratio of 0.71. The first contained an ordinary Portland cement and the second contained the same cement blended with Rutile (a fine, non-hydraulic filler).
