Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.

The chief chemical components of portland cement are calcium, silica, alumina and iron. Calcium is derived from limestone, marl or chalk, while silica, alumina and iron come from the sands, clays and iron ore sources. Other raw materials may include shale, shells and industrial byproducts such as mill scale (Ash Grove Cement Company, 2000).

Slag and fly ash complement each other in a composite cement. Composite cement made with 60% OPC + 30% fly ash + 5% limestone powder has higher strength than PPC made with 30% fly ash. 2.3 Production of multi-component cements enables not only fuel energy savings (by 30-40%) but also increased volumes of concrete production.

CementandConcreteBasics. In its simplest form,concreteis a mixture of paste and aggregates. The paste, composed of portlandcementand water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known asconcrete.
