What is cement raw materials?

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. Chalk is soft raw material, it does not require crushing. Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay.

Can you make cement at home?

Cement, in fact, is one of several ingredients that are combined to make concrete. Cement is a powdery, dry substance that makes concrete when it’s mixed with water, gravel, and sand. Instead of buying a bagged mix, you can try making your own cement by obtaining and burning limestone.
