power generation from waste heat in cement manufacturing

Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker
