PCEs are adsorbed on to the surface of cement particles through their negatively charged anchoring groups (which include carboxyl teams) to kind a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, thus enhancing the flowability on the cement slurry. There are lots of types of superplasticizers used in construction. https://beaulmeya.prublogger.com/36664792/how-foaming-agent-for-concrete-can-save-you-time-stress-and-money
