    The raw materials needed to produce cement (calcium carbonate silica alumina and iron ore) are generally extracted from limestone rock chalk clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
