PCEs Are adsorbed onto the surface of cement particles through their negatively charged anchoring groups (which include carboxyl groups) to sort a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, therefore enhancing the flowability with the cement slurry. Superplasticizers are predominantly used in pumping concrete, casting seriously reinforced associ... https://modtc-cas-no-253873-83-564073.birderswiki.com/1771713/pce_admixture_things_to_know_before_you_buy
