CO2 Emissions Profile of the U.S. Cement Industry

After the clinker is cooled, the clinker nodules are ground into a super-fine powder in a horizontal tube containing steel balls. During the finish grinding process, the type of cement is determined based upon the type and quantity of additives added. Cooled clinker can be mixed with a small quantity of gypsum to produce Portland cement or can be

History of Cement - World Cement Association

The precursor to modern-day cement was created in 1824 by Joseph Aspdin, a British bricklayer and builder, who experimented with heating limestone and clay until the mixture calcined, grinding it and then mixing it with water. Aspdin named this Portland Cement, after the famously strong building stone from the Isle of Portland in Dorset, UK.

Cement mill - Wikipedia

History. Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were relatively soft and readily ground by the primitive technology of the day, using flat millstones.The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material.
