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
