PCEs Are adsorbed onto the surface of cement particles by their negatively charged anchoring groups (for example carboxyl teams) to kind a thicker adsorption layer, building electrostatic repulsion and steric hindrance, thereby enhancing the flowability on the cement slurry. Lignosulfonates or sulfonated lignins are water-soluble anionic polyelectrolyte polymers, they are https://cristianbzxts.tinyblogging.com/superplastificeerder-voor-beton-an-overview-81507100
