portland cement raw material

Use of raw materials in the cement industry

A responsible raw materials policy must therefore create reliable framework conditions for sustainable supply of raw materials. This is the only way that companies will be able to obtain the planning and investment security required to continue to be able to cover requirements for topquality cementbound building materials in future.
