Effect of cooling rates on mineralization in Portland

2015 8 12   The rate at which cement clinker is cooled as it exits the kiln has long been known to be an important factor in cement quality. Cooling rate is one of the variables that has a significant impact on the minerals produced during the cement making process. The goal of the industry has been to produce cement clinker containing minerals that are highly reactive with water.

2021 7 27   During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter. Pure cement is formed when the cement clinker is ground into a fine powder. To regulate how cement mortar or concrete will set, gypsum is added to this powder.
