Cement Production by Milling can Reduce CO2 Emissions
Environmentally destructive calcination of lime is evaded by grinding raw lime with sodium silicate. Chemists at Johannes Gutenberg University Mainz (JGU) in Germany have recently formulated a technique that could significantly decrease CO 2 emissions from cement production. In this approach, the raw lime (CaCO 3) is no longer turned into burnt lime in coal …
