3. Alternative raw material use in the cement industry Waste derived or byproduct materials can be utilised from cement industries in multiple ways: • to replace primary raw materials used in the cement clinker recipe • to substitute conventional fuels such as coal, coke, and gas.

Where is cement used?

Cement plays a key, but often unnoticed, role in our lives. Cement is mainly used as a binder in concrete, which is a basic material for all types of construction, including housing, roads, schools, hospitals, dams and ports, as well as for decorative appliions (for patios, floors, staircases, driveways, pool decks) and items like tables, sculptures or bookcases.
