PCEs Are adsorbed onto the surface of cement particles as a result of their negatively charged anchoring groups (for instance carboxyl teams) to type a thicker adsorption layer, making electrostatic repulsion and steric hindrance, thereby enhancing the flowability in the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions https://aerogel-blanket04714.wikipublicity.com/7406378/rumored_buzz_on_air_entraining_agents
