PCEs are adsorbed on to the surface of cement particles via their negatively billed anchoring teams (like carboxyl groups) to variety a thicker adsorption layer, creating electrostatic repulsion and steric hindrance, thus enhancing the flowability of the cement slurry. There are lots of types of superplasticizers used in construction. These https://waylonjpnic.csublogs.com/45042596/the-ultimate-guide-to-air-entraining-agents
