PCEs are adsorbed onto the surface of cement particles as a result of their negatively charged anchoring groups (which include carboxyl groups) to kind a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, therefore enhancing the flowability with the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions https://redispersible-polymer-pow82582.blog4youth.com/38255029/an-unbiased-view-of-concrete-additives-for-strength
