PCEs are adsorbed on to the surface of cement particles through their negatively charged anchoring teams (which include carboxyl groups) to sort a thicker adsorption layer, producing electrostatic repulsion and steric hindrance, thereby enhancing the flowability with the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions are required https://carbon-fiber-filament26036.techionblog.com/37773794/a-secret-weapon-for-air-entraining
