PCEs are adsorbed onto the surface of cement particles through their negatively charged anchoring groups (which include carboxyl groups) to kind a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, thereby enhancing the flowability with the cement slurry. There are several types of superplasticizers used in construction. These tumble https://modtpcasno72030-25-203603.idblogz.com/38065099/facts-about-super-plasticizer-revealed
