The cement industry is making great efforts to reduce the high CO2 emissions generated during cement production.
One important objective – among many others – is to reduce the proportion of clinker, which is the main source of CO2 emissions. This report explains the consequences of using CO2-reduced cements on the curing process of concrete
products.
The production of cement and concrete accounts for a significant proportion of global CO2 emissions. The largest share is caused by the production of cement clinker, the main component of cement. Cement clinker is produced by burning limestone (CaCO2) in rotary kilns at around 1450 °C. In this process, about two-thirds of the CO2 emissions are produced
by the chemical conversion of limestone to calcium oxide (CaO) and CO2. The remaining third can be attributed to the combustion of fossil fuels such as coal, gas or oil, which are
essential for achieving the high firing temperatures.... (read more in the full article)
