ordinaryportland cement: uses, advantages & disadvantages

A large amount of alumina accelerates the setting but weakens the cement. Iron Oxide: The high volume of iron oxide will make the cement difficult to fuse and form clinker. High ferric oxide content is favourable to the production of high early strengths in cement. Magnesia: The magnesium content shall not exceed 5.0 % by mass
