Cement

What is the role of cement in clean energy transitions? Key strategies to cut carbon emissions in cement production include improving energy efficiency, switching to lower-carbon fuels, promoting material efficiency (to reduce the clinker-to-cement ratio and total demand), and advancing innovative near zero emission production routes.

Cement Production

Cement production has undergone a tremendous development from its beginnings some 2000 years ago. While the use of cement in concrete has a very long history, the industrial production of cements started in the middle of the 19th century, first with shaft kilns, which were later on replaced by rotary kilns as standard equipment worldwide.

New approach suggests path to emissions-free cement

A variation of this process can be used to convert calcium carbonate (CaCO 3) into calcium hydroxide (Ca(OH) 2), which can then be used to make Portland cement without producing any greenhouse gas emissions. Cement production currently causes 8 percent of global carbon emissions.

How Cement is Made

Stage of Cement Manufacture. There are six main stages of the 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 into smaller …

How cement and concrete are made

This results in the production of cement clinker, an intermediate product in the manufacturing process. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat the kiln account for about 40% of cement-manufacturing emissions.
