Colloidal theories have been applied successfully to cement suspensions. Interparticle forces, important in the attractive networks formed by cement pastes, have been described and some of the limitations, often ignored until now, explored and discussed with reference to recent literature. How the complex pore solution met in cement pastes may be represented by a non integer charge, how electrostatic forces induced by superplasticizer adsorption and how the particle size distribution of cement particles can effect interparticle force calculations are discussed and demonstrated. Measurements of zeta potentials using multi frequency acoustophoretic analysis for ultra-fine cements are also presented.
