Calcium aluminate cements〔Hewlett P.C. (Ed.) (1998) ''Lea's Chemistry of Cement and Concrete: 4th Ed'', Arnold, ISBN 0-340-56589-6, Chapter 13.〕 are cements consisting predominantly of hydraulic calcium aluminates. Alternative names are "aluminous cement", "high-alumina cement" and "Ciment fondu" in French. They are used in a number of small-scale, specialized applications. ==History== The method of making cement from limestone and low-silica bauxite was patented in France in 1908 by Bied of the Pavin de Lafarge Company. The initial development was as a result of the search for a cement offering sulfate resistance. The cement was called in the French "Ciment fondu". Subsequently, its other special properties were discovered, and these guaranteed its future in niche applications.
