Abstract

244,756. Spackman, H. S. Dec. 17, 1924, [Convention date]. Cements, Portland, processes for making.-In the manufacture of hydraulic cements having a low lime content and a high content of acidic oxides by melting a charge consisting of a basic material such as lime and an acidic component such as alumina, iron oxide, silica, or titanium, oxidizing conditions are maintained in the furnace to prevent reduction of iron compounds to the metallic or ferrous states. A rotary kiln is preferably used and the oxidizing conditions are obtained by control of the air blast. The raw material may consist of equal parts of bauxite and limestone. Specification 222,151 is referred to. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the manufacture of hydraulic cements other than those defined above. This subject-matter does not appear in the Specification as accepted.
