Concrete Scientific Principles

The production of portland cement begins with the quarrying of limestone, CaCO 3. Huge crushers break the blasted limestone into small pieces. The crushed limestone is then mixed with clay (or shale), sand, and iron ore and ground together to form a homogeneous powder. However, this powder is microscopically heterogeneous.
