Minerals are solid substances that have formed naturally in the Earth. They The cement manufacturing process involves crushing, blending and melting, at extreme temperatures, local limestones, clays and shales. These rocks, which are quarried close to the cement factories, provide us with the four basic ingredients that are essential for cement, Calcium, Silicon, Aluminium and Iron.
