The first forms of clinkerbased hydraulic cements contained basic calcium compounds, for which the major raw materials are limestone (calcium carbonate) and clay (silicon oxide compounds). Calcination (from the Latin word calcinare) is the decomposition of calcium carbonate (limestone) to calcium oxide (lime) in order to produce basic cement. The product of calcination is usually referred to, in general, as .

Portland cement is a basic ingredient of concrete, mortar, and most nonspecialty grout. The most common use for Portland cement is to make concrete. Concrete is a composite material made of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape, and once it hardens, can be a structural (load bearing) element.
