Get Price· The MIP test results show that the addition of clay improves the micropore structure in the cement paste and limits the introduction of chloride ions. SEM imaging suggests that the kaolinite clay is acting as both filler and accelerator of cement hydration. It is found that the addition of clay alters the water requirement of normal consistency and the setting time of .
Get Price· The polycondensation a process for the production of polymers from bifunctional and polyfunctional compounds (monomers), accompanied by the elimination of lowmolecular weight byproducts (for example, water, alcohols, and hydrogen halides).
