The aim of the presented work was to study the dependence of the SiO2 sol zeta potential on the contents of calcium chloride. The sol contained 2.27 wt. % of SiO2 and the content of anhydrous CaCl2 varied between 0.126 and 13.0 wt. %. The experiments demonstrated an influence of calcium and chloride ions on the electrokinetic potential. Formation of gels based on calcium-silicate hydrates can be expected with an increasing content of calcium ions in the solution. On the other hand, increasing content of chloride ions brings about a lowering of the pH of the solution, thus slowing down the transport of the silicate components into the solution. These chloride effects are more apparent at higher CaCl2 concentrations. The described phenomenon explains the behaviour of calcium chloride as an additive accelerating the hydration of the silicate components of clinker minerals.
