Cement Analysis

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

Oxyfuel a climate neutral cement production is getting closer

05 06 2019  In recent years the cement industry has done a great deal to reduce its pollutant emissions Nevertheless large quantities of CO2 are still emitted during cement production 60 percent of this is produced in the intermediate calcination step alone when limestone is deacidified in other words CO2 is separated from the calcium carbonate and processed into cement clinker.
