Clinker (cement) - Wikipedia

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stageCement - Wikipedia,A cement is a binder, a substance used for construction that sets, hardens, To reduce the transport of heavier raw materials and to minimize the associated costs, it is more economical to build cement plants closer to the limestone quarries rather than to the consumer centers,
