Chemistry of the calcite/water interface: Influence of sulfate ions and consequences in terms of cohesion forces

Calcite suspensions are used to mimic the behavior of more complex cementitious systems. Therefore the characterization of calcite–water interface in strong alkaline conditions, through ionic adsorption, electrokinetic measurements, static rheology and atomic force microscopy is a prerequisite. Calc...
