Clinkers and cement were produced from these mixes and tested. The data indicated that clinkers had normal formation and distribution of the major clinker phases, and the cement had strength and setting properties comparable to that produced at the actual cement plants. A cement plant in Canada has also used upto 10 % high carbon fly ash as a ...
Equation 10: Clinker mass balance For the clinker mass balance at plant level this means: B + S start + C in + K in + P = D + S end + C out + K out + M. where: B = the clinker which is bought from other companies.; S end = the amount of clinker in stock at the end of the reporting year; C in = the amount of clinker in cement which is received from other plants of the …
