METHOD FOR CARBONATING WASTE MATERIALS
Method for improving the reactivity of carbonated recycled concrete paste comprising sulfur in an oxidation state lower than 6+ as supplementary cementitious material comprising the steps: - providing a starting material comprising recycled concrete paste, - carbonation of the starting material with carbon dioxide contained in an exhaust gas containing from 2 to 15 Vol.-% oxygen and/or from 35 to 400 vppm sulfur dioxide to provide carbonated recycled concrete paste, and - oxidation of the carbonated recycled concrete paste simultaneously or subsequently to the carbonation with an added oxidizing agent to provide the supplementary cementitious material, and method for making composite cements.
