PCEs are adsorbed onto the surface of cement particles by their negatively charged anchoring groups (for instance carboxyl teams) to sort a thicker adsorption layer, producing electrostatic repulsion and steric hindrance, thus enhancing the flowability of the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions are necessary to https://paxtonkkigc.blazingblog.com/37613474/details-fiction-and-polycarboxylate-ether-superplasticizer
