How is concrete made from limestone? | Shelly Company

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