Colloid-Chemical Investigation of the Interaction Between PCE Superplasticizers and a Calcined Mixed Layer Clay
Abstract This study investigates the dispersing performance of three different polycarboxylate superplasticizers (PCEs) and a cationic polymer in the suspension of a calcined clay holding a mixture of different meta phases. It was found that the anionic PCEs as well as the cationic polymer can disperse this clay, thus suggesting that this calcined clay exhibits particles with positive as well as negative surface charges. Relative to PCEs, their dispersion ability is highest when their anionicity is particularly high. Adsorption and zeta potential measurements of the PCEs further elucidated this interaction.
