A Contribution towards a More Sustainable Cement: Synergy of Mill

The raw materials used for the preparation of the raw meals were limestone, shale, lava, ILS and WFA. Limestone and shale are quarried raw materials which are typical in cement production due to their oxide content in CaO, SiO 2, Al 2 O 3 and Fe 2 O 3. Lava is the solidified form of the magmatic material (Τ = 700–1200 °C).The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO<sub>2</sub> emissions.
