Cement-Cement- Extraction andprocessing: Raw materials employed in the manufacture ofcementare extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.Get Price
Cement is manufactured through a closely controlled chemical combination of calcium,silicon,aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.Get Price
