Abstract: A method for producing a foamed mineral binder composition includes the steps of: a) separately providing: (i) an aqueous foam; and (ii) an aqueous slurry including a mineral binder and a dispersed polymer; (b) mixing the slurry of the mineral binder with the aqueous foam to obtain the foamed mineral binder composition; whereby during the production of the foamed mineral binder composition, carbon dioxide and/or a carbonate is provided such that it is incorporated in the foamed mineral binder composition.

Abstract: Methods for the retrieval of aggregates from waste construction material by grinding in a ball mill or on a compressive grinder, which are useful in the recycling of waste construction material, especially in the recycling of concrete or mortar. Also, cleaned aggregates obtained from waste construction material by grinding and their use on the production of new construction materials.
