2018-3-29  This gel evolves with time, getting “structured” and forming colloidal crystals that connect cement grains. All additives and admixtures that work on the plastic phase of cement paste interact with this gel and become part of it, modifying its structure in terms of quantity and quality. These modifications also depend on the chemical composition of the cement itself.
