Abstract
250,246. Soc. Anon. des Chaux et Ciments de Lafarge et du Teil. April 4, 1925, [Convention date]. Cements, Portland, processes for making. - Aluminous cements are made by heating the raw materials in a very fine state of subdivision to a temperature below the clinkering point, preferably 1000-1100‹ C. It is unnecessary to use pure materials, and limestone, clay, hydraulic lime, iron ore, and siliceous, silico-aluminous, and silico-alumino-calcareous rocks may be utilized. The composition of the resulting cement may be varied within wide limits, namely, silica 0-5 per cent, alumina 40-55 per cent, iron oxide 10-25 per cent, and lime 20-40 per cent. Reference has been directed by the Comptroller to Specification 243,876.
