Limestone calcined clay cement and concrete: A state-of-the-art review ...

Trials of intergrinding of clinker, limestone, calcined clay and gypsum have shown that the softer nature of limestone and clay and the harder nature of clinker lead to a bi-modal particle size distribution of the cement [29,58]. While the clay and limestone particles may be ground too fine, the clinker particles remain coarse.

How is concrete made from limestone? | Shelly Company

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.
