PCEs are adsorbed on to the surface of cement particles through their negatively charged anchoring teams (which include carboxyl groups) to kind a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, therefore enhancing the flowability with the cement slurry. Lignosulfonates or sulfonated lignins are water-soluble anionic polyelectrolyte polymers, they https://sphericalmolybdenumpowder72480.newsbloger.com/38351466/the-ultimate-guide-to-air-entraining-agents
