  • Clinker (cement) - Wikipedia

    In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

  • Cement Kilns: Clinker

    Clinker minerals react with water to produce the hydrates that are responsible for cement’s setting and strength-giving properties. Reaction with water occurs only at the surface of the clinker particle, and so only proceeds rapidly if the clinker is finely ground to produce a large reaction surface. Un-ground clinker, when exposed to humid air, is hydrated only very gradually, and clinker ...

    Alluvial clay was the first to be used in Portland cement in the Thames valley (and although the source of clay used by Joseph Aspdin in Yorkshire is unknown, it was most probably also alluvium). Early cement manufacturers ascribed almost magical qualities to the alluvium of the Medway estuary, and even distant plants (e.g. Shoreham ) used it, obtaining supplies by coastal barge.
