To make cement, raw materials such as limestone, cement rock, sand, iron ore, clay and shale are crushed, blended and fed into a kiln. These materials are then heated in the kiln to temperatures above 2900°F to initiate a chemical reaction (called "fusion") that produces cement "clinker," a round, marble-sized, glass-hard material.
