CEMENT PRODUCTIONCement production is the manufacture of hydraulic cement from rock usually quarried by the manufacturer The principal cement product is Portland cement, patented in England in 1824 and originally used as a substitute for lime mortar, but small quantities of natural cement and pozzolana are also manufactured
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together There are two main forms of cement: Geopolymer cement and Portland CementCement is seldom used on its own, but rather to bind sand and gravel togetherCement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete
IX-Materials-B-Cement-1 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 hundred-fold
