recycling process of limestone

Calcium Carbonate Concrete: Building on Recycling

2021-10-12  In general, concrete is made from ordinary cement, where one of the resources is limestone (CaCO 3).To obtain the CaO from the limestone, the cement industry must emit CO 2 by decomposing limestone.. Therefore, CO 2 emission is an inevitable process for the current cement concrete industry. At the same time, the concrete waste can be recognized as an urban mine of CaO.
