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, thereby enhancing the flowability with the cement slurry. Superplasticizers are predominantly used in pumping concrete, casting https://israelfaskc.educationalimpactblog.com/59050976/the-hpmc-diaries
