Abstract

282,755. Soc. Anon. de MatÚriel de Construction. Dec. 29, 1926, [Convention date]. Void [Published under Sect, 91 of the Acts]. Cements, Portland, materials and compositions for.-The decomposition of calcium sulphate by ammonium carbonate to form ammonium sulphate and calcium carbonate is carried out in presence of clay, kaolin, bauxite or other substances containing silica, alumina and oxide of iron, so that the pasty residue after separation of ammonium sulphate solution is suitable for making Portland cement. A mixture with water of gypsum, clay, kaolin, &c. is treated with ammonia gas or mixed with ammoniacal liquor, and carbon dioxide under pressure is passed through. The temperature is maintained preferably at 34-45‹ C. at the commencement and is regulated so as not to rise above 75‹ C. Carbon dioxide recovered in the making of cement may be used again in the process.
