<p>Building material mixture for producing moulded and prefabricated elements, such as, for example, bricks, sheets, supports, pipes, etc., consisting of a basic raw material component in an amount of 85 to 100, preferably 90.6 to 95.4, % by weight, if necessary a binder, preferably slaked lime or quicklime in an amount of 0 to 15, preferably 4.6 to 9.4, % by weight, and water. The basic raw material component consists of tribomechanically activated domestic and/or industrial wastes, in particular of slags and ashes from waste incineration or power stations, of brick and/or concrete waste or wastes from brick and/or concrete production, etc., and the weight ratio of mixture to water is 1 : 0.05 to 1 : 0.25. The invention also relates to a process for the production of such building material mixtures.</p> |
