  • 3.4 Burning in a kiln – clinker formation

    Once the nodules of cement clinker have cooled, they are ground back into a fine powder in a large grinding mill. At the same time, a small amount of calcium sulfate such as gypsum (calcium sulfate dihydrate) is blended into the cement. The calcium sulfate is added to control the rate of early reaction of the cement, as will
