Effect of the Physical and Chemical Characteristics of Polycarboxylate Ether Superplasticizers on the Spreading of Calcined Clays with Different Metakaolinite Contents Suspended in Synthetic Cement Pore Solution
> 1 in intermediate cases), while stabilizing-rich variants showed rapid loss. Zeta potential values remained close to zero due to the high ionic strength of the SCPS, indicating that electrostatic interactions play only a secondary role in the dispersion process, while steric effects govern the performance of the investigated PCEs. Overall, optimal PCE selection requires matching polymer architecture to clay reactivity for effective dispersion and fluidity retention in sustainable calcined clay systems.
