Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. the grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. if the limestone used in the cement manufacturing process is of high grade then lowgrade coal is used and vice versa.

Different types of limes used in construction are quick lime, slaked lime, fat lime and hydraulic lime. they are obtained by the process of calcination of natural limestone overemperature of 900degree celsius. every form of lime is highly versatile and is used in environmental, construction, chemical and metallurgical industries.

9.2. occupational health. limestone principally calcium carbonate isaturally occurring mineral and is found widely throughout the world. it is mainly used for road construction, in the production of concrete and astructural fill. it is also the principal raw material for the production of cement, quicklime, and numerous other products.

Apart from this, it is used in the steel industry for the production process where limestone is used to remove impurities. the minerals found in limestones are also used in pharmaceuticals, cosmetic products, baking soda, toothpaste, etc. construction and architecture. here limestone is quarried to service the needs of the building and construction industries.
