RAW MATERIALS IN CEMENT PRODUCTION

 · The choice of composition of materials mixture with useful components generally is determined by plant''s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.Cement – Analysis - IEAAdopting material efficiency strategies to optimise the use of cement can help reduce demand along the entire construction value chain, helping to cut CO2 emissions from cement production. Therefore, demand in 2030 in the Net Zero Emissions by 2050 Scenario is 6% lower than in a baseline scenario in which no steps are taken to reduce demand.
