Use of alternative fuels and by-products materials. A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.
Raw materials Composition. Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material.
We use alternative raw materials for the production of clinker, which is the most important intermediate product in the manufacture of cement. In this way we reduce the amount of CO 2 intensive clinker in the final product. The increased use of alternative raw materials in cement production is thus a core element of our climate strategy. At ...
