Clinkeris a nodular materialproducedin the kilning stage during theproductionofcementand is used as the binder in manycementproducts. The lumps or nodules ofclinkerare usually of diameter 3-25 mm and dark grey in color. It isproducedby heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
