Report on Cement manufacturing process
7/8/2016 · Report on Cement manufacturing process The main measure of fineness today is specific surface. Because cement particles react with water at their surface, the specific surface area is directly related to the cement''s initial reactivity. By adjusting the fineness of grind, the manufacture can produce a range of products from a single clinker.

Properties of Cement Physical & Chemical Civil Engineering
Ferrite is a fluxing agent. It reduces the melting temperature of the raw materials in the kiln from 3,000°F to 2,600°F. Though it hydrates rapidly, it does not contribute much to the strength of the cement. Magnesia (MgO) The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants.
