PCEs are adsorbed onto the surface of cement particles by way of their negatively billed anchoring groups (including carboxyl teams) to form a thicker adsorption layer, creating electrostatic repulsion and steric hindrance, thus enhancing the flowability of the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions are required https://holdenhiged.dailyblogzz.com/38221419/top-guidelines-of-plasticizers-in-concrete
