PCEs are adsorbed onto the surface of cement particles through their negatively billed anchoring groups (including carboxyl groups) to form a thicker adsorption layer, building electrostatic repulsion and steric hindrance, therefore enhancing the flowability from the cement slurry. Lignosulfonates or sulfonated lignins are water-soluble anionic polyelectrolyte polymers, they are bypro... https://carbon-fiber-filament82469.ageeksblog.com/36294414/concrete-release-agent-fundamentals-explained
