The addition of grinding aids to the clinker in cement

May 07, 2019 To reduce agglomeration during the grinding of clinker, grinding aids are usually added in the range of 0.02% to 0.1% of the manufactured cement weight. Chemical basis of the grinding aids includes ethanolamines, such as triethanolamine, monoethanolamine, and tri isopropanolamine, as well as glycols, such as ethylene glycol and propylene glycol.

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 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
