Variation in CaO content from 24% to 42% was observed with an increment in SiO 2 content, as some of the aggregates might have crushed into finer fractions while crushing the concrete CDW. The presence of CaO, MgO and Fe 2 O 3 oxides in these fines show the potential to form thermodynamically stable carbonates through mineral carbonation.
