Whilst there have already been numerous types of superplasticizers, that are all based on OPC, the component mo

PCEs are adsorbed onto the surface of cement particles via their negatively billed anchoring groups (such as carboxyl teams) to type a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, thus enhancing the flowability in the cement slurry. Superplasticizers are used when well-dispersed cement particle suspensions a
