What remains are small grey balls like marbles which are called clinker. Clinker Is Ground Into Powder. After the clinker is cooled, its ground up and crushed it intoLimestone breaks down into calcium oxide, silicon oxides, and carbon dioxide. These are mixed and combined in order to produce tri-calcium silicate, which is turned into a fine powder that we usually know as a clinker. Lastly, gypsum is added to the clinker, and this results in cement, the main ingredient of concrete.
