Cement Manufacture

Cement Manufacture. Cement manufacture begins when feedstocks enter the raw mill, creating a fine powder (so-called ‘raw meal’) in which 85% of material is smaller than 88μm (Alsop et al., 2007). From: Science of The Total Environment, 2011. Download as PDF

Cement – Analysis - IEA

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise was the

Similarly, relatively little energy is used in producing and combining the raw materials (although large amounts of CO 2 are produced by the chemical reactions in cement manufacture). The overall embodied energy of concrete at roughly 1 to 1.5 megajoules per kilogram is therefore lower than for most structural and construction materials
