There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches. Energy Consumption in Production of Concrete Aug 28, 2017  The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning , which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil . Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions. FACT SHEET Energy use in the steel industry the energy used during their production.

World Energy Consumption Statistics Enerdata Global energy consumption growth slowed down in 2019 (+0.6%) compared to an average 2%/year over the 2000-2018 period, in a context of slower economic growth. Energy consumption increased at a slower pace than in previous years in China (+3.2%), the world’s largest consumer since 2009, in Russia (+1.8%) and in India (+0.8% only). New measures for energy saving and consumption reduction In China, energy conservation and consumption reduction have always been placed in the cement industry, and achieved certain results. However, the energy consumption of the cement industry has not been fundamentally changed, especially in large-scale cement production, and reducing energy consumption is still the main direction of the future.
