PCEs are adsorbed onto the surface of cement particles by their negatively charged anchoring groups (for instance carboxyl teams) to kind a thicker adsorption layer, building electrostatic repulsion and steric hindrance, thereby enhancing the flowability on the cement slurry. There are various types of superplasticizers used in construction. These drop https://spherical-niobium-powder60369.eveowiki.com/1841132/the_hpmc_diaries
