Earlycementmanufacturers ascribed almost magicalqualitiesto the alluvium of the Medway estuary, and even distant plants (e.g. Shoreham) used it, obtaining supplies by coastal barge. The key quality of theclay, not identified until much later, was the content of fine silica, in addition toclayminerals, and the existence of highly-prized ...

Cementclinkeris a solid material produced in the manufacture of Portlandcementas an intermediary product.Clinkeroccurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such asclayduring thecementkiln stage.

Technically, acementproducer can have almost complete control overclinkercomposition by blending raw materials of different compositions to produce the desired result. In practice, however,clinkercomposition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
