PCEs are adsorbed onto the surface of cement particles by means of their negatively charged anchoring groups (like carboxyl groups) to form a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, thus enhancing the flowability of the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions are needed https://jareddedok.qodsblog.com/37739919/fascination-about-our-special-cement-concrete-formulas-are-engineered-for-extreme-environments-and-niche-applications-specialcement-advancedconcrete-constructioninnovation-https-www-cabr-concrete-com
