chemical components of portland cement with uses


  • Cement Chemistry

    Cement chemistry is sensitive to the components of the combustion products. Some contain chlorides. Chlorides and other anions hinder the setting of cement and corrode metal rebars used to reinforce cement structures. 2. The carbon content in ash is also a major factor. High-carbon ash hinders setting of cement.
