Abstract

221,017. Schmidt, O., and Hahnle, M. June 6, 1923. Cements, processes for making; concretes.- Hydraulic cement and artificial stones or concrete are made from oil-shale slag obtained bv the burning, below the limit of sintering, of oilshale or of the residues of the distillation of oilshale (shale-coke). The slag is broken up and sifted, the fine part being used for making cement, and the coarse part is moistened with cold or hot water or steam for several days to destroy sulphides and slake the lime, and then mixed with the cement made from the fine part to form artificial stones or concrete. To form the cement, the fine part is ground with burnt marl (preferably a. marl which in unburnt condition contains 50-75 per cent of calcium carbonate) or with cement, with or without the addition of anhydrous calcium sulphate or suitable hydraulic substances such as blast furnace slag which has been granulated by water or by a current of air. The marl mav be mixed with the oil-shale or shale-coke and burnt therewith, with or without the addition of necessary combustible matter.
