  • Cement Chemistry - an overview ScienceDirect Topics

    Cement chemistry can affect the dispersion efficiency of superplasticizers in various ways. One of these is through the ionic composition of the aqueous phase and in particular through the amount of soluble sulfates. The milestone paper on this subject comes from Yamada and Hanehara (2001).As explained in Section 7.3.1 on the reversibility of polymer adsorption, they made alternative additions ...
