The Manufacture of Portland Cement

THE MANUFACTURE OF PORTLAND CEMENT Cement is the substance which holds concrete together, which means that it is extremely widely used in our society It has been manufactured in New Zealand for more than 100 years, and during this century production has increased one hundredfold Portland cement (the only type of cement in common use today) is manufactured in a four step

Manufacture of Portland cement University of Technology

The raw materials used in the manufacture of Portland cement consist mainly of lime, silica, alumina and iron oxide These compounds interact with one another in the kiln to form a series of more complex products and, apart from a small residue of uncombined lime which has not had sufficient time to react, a state of chemical equilibrium is reached The resultant of firing is the clinker Four
