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 known as "Ciment fondu" in French. Subsequently, its other special properties were discovered, and these guaranteed its future in niche applications. By the 2010s, the product was found in the US market under the name FONDAG cement (FOND Alumi
