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

ELEMENTAL CHEMISTRY: Manufacture of Cement

Oct 27, 2020  The essentials raw materials for the manufacture of cement are limestone and clay which supply all the four principal ingredients, such as CaO, Al 2 O 3, SiO 2, and Fe 2 O 3. Calcium oxide and iron oxide, these both substance are obtained from limestone, while silica and alumina are obtained from the clay. Thus raw materials are two types---
