Why is limestone used to make cement? | AnswersDrive

To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

Our Portland Limestone Cement offers the same level of performance and workability you expect from standard Type I and Type II cements. But, because it's manufactured with quality limestone, it uses less clinker than the traditional manufacturing process and reduces CO 2 emissions by five to 10 percent per ton of cement. Why's that important?
