Color control: The gray of cement - BFT INTERNATIONAL

In Portland cement, this in large part depends on the iron content in the clinker – the higher it is, the darker the gray becomes because of the magnesium in the cement. For example, in the Paderborn cement plant, we have a rather dark cement because its iron content is high, while at the plant in Geseke, we have a lighter-colored cement with a lower iron content.
