Series The Global Cement Industry Cement is a basic ingredient for the construction industry. Cement is made out of limestone‚ shell‚ clay mined out of a quarry close to the plant. The raw material is crushed‚ and then heated at temperature in excess of 1000 ºC in rotating kiln to become clinker. Clinker is then mixed with gypsum and ground to a fine powder to produce final grade of cement. The technology is a continuous process and is highly energy intensive. Cost of cement is 29% energy‚ 27%
