Abstract

Products containing calcium aluminate and obtained by treatment of highly aluminous material with lime are subjected to the action of carbon dioxide to carbonate the free lime and loosely combined lime. The resulting cement resembles ordinary aluminous cement in hardening properties but is more plastic. The treatment with carbon dioxide may be effected by passing the material through an inclined rotating cylinder through which furnace gases at 500-700 DEG C. pass in counter-current. The treatment is particularly applicable to products obtained by treating alumina and lime with steam, e.g. at 200 lb. pressure for about three hours. It is also applicable to the products obtained by first treating the raw materials with steam and then heating to about 1000 DEG C. as described in Specification 303,639, [Class 22, Cements &c.], or to products obtained by the action of heat without steam treatment.
