Abstract

222,122. Martin, E. Sept. 17, 1923, [Convention date]. Cements, Portland &c., materials and compositions for.-A cement is made by burning a mixture containing iron oxide and calcium carbonate, at a temperature below the melting point of the mixture, the proportions of the mixture being more than two molecules of calcium carbonate to each molecule of iron oxide, and one molecule of lime! for each molecule of alumina, and two molecules for each molecule of silica, if the latter is present. Suitable raw materials are iron pyrites cinders, iron ores, ochres, and sludge from alumina foundries. According to an example, 160 kilos of pyrites cinders and 300 kilos of limestone are mixed wet. or dry, and are burnt in a rotary or other kiln at a temperature of about 1100‹ C. Specification 3768/01 is referred to.
