Abstract

303,639. Knibbs, N. V. S. Dec. 16, 1927. Cements, Portland and Roman.-A cement of the high alumina type is produced by subjecting a mixture of lime and bauxite or other highly aluminous material to the action of steam, preferably under pressure, to secure reaction between the raw materials, and then subjecting the resultant product to a higher temperature which is normally however below the melting- point. The proportions may vary from one to two parts of lime to three parts of bauxite. The bauxite is ground and mixed with either quick or hydrated lime. The steam treatment when carried out at a pressure of 100 lbs. per square inch may be completed in one hour. The heat treatment may be at a temperature between 1000‹ and 1400‹ C. With bauxite containing 50 per cent alumina and 20 per cent iron oxide, four hours heating at 1100‹ to 1150‹ C. is sufficient, or two hours at 1150‹ to 1200‹ C.
