Cement is a finely milled mineral powder, usually grey in colour. The most important raw materials for the production of cement are limestone, clay, and marl. Mixed with water, cement serves as an adhesive to bind sand, gravel, and hard rock in concrete. Cement hardens both in the air and under water, and remains in its hardened state once reached.

Cement is usually available in the form of a homogeneous bulk dry good. It’s characteristics are standardised in order to ensure the required stability, reliability, and processability in the application.
