Scientific Processes For Cement Production

  • The Importance of Cement and its Future | Cement Science

    Concrete is the most used material in the world because of its cheap price and large quantity. It is needless to say concrete is made of cement. However, cement is also a criticized material by the public, for its intensive CO 2 emission from production process. The production of cement accounts for about 5-8% of the non-natural CO 2 worldwide.
