PCEs are adsorbed on to the surface of cement particles through their negatively charged anchoring teams (such as carboxyl groups) to kind a thicker adsorption layer, generating electrostatic repulsion and steric hindrance, thereby enhancing the flowability on the cement slurry. This might involve laboratory exams to measure water reduction, slump https://nanosiliconpowder93603.shivawiki.com/7708303/an_unbiased_view_of_concrete_additives_for_strength
