Improving Concrete Sustainability
The lower limestone content in the raw materials leads to a reduction in CO 2 emissions from calcination. As about half of limestone is CO 2, 120 kg/ton translates into roughly 60 kg/ton of reduced CO 2. The net savings in CO 2 emissions might be on the order of 10% to 15%, without considering any grinding energy changes.
