What is Cement Clinker? Composition, Types & Uses Civil
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kilnfluxes to reduce the clinkering temperature and accelerate the formation of the main mineral phases (10, 12, 13), the use of mineral additions to the cement (puzzolans and fillers) to lower the clinker/ cement ratio (14), alternative cements (10, 15, 16), and the development of highperformance concrete (17), among othersOptimal fluorite/gypsum mineralizer ratio in Portland
