CIMENT FONDU LAFARGE is the world's first commercially manufactured calcium aluminate cement, patented by J. Bied of Lafarge in 1908. The initial preparation was in response to the demand for sulfate resistant cement. Since then, subsequent research and product development revealed other properties of the cement that transformed it from being just a sulfate-resistant cement into a raw material for specialized applications that depend on its chemical, mineralogical and physical properties. It has also led to the development of a family of calcium aluminate products, with a wide range of properties that can fulfill many industrial requirements.

FONDU cement is one of three calcium aluminate cements available in North America derived from a fused clinker. Dark brown in color, this is the darkest of the three cements. The clinker for this cement is prepared in one of Lafarge's two production facilities in France using a reverberatory furnace in which the raw materials are melted to form the clinker. The fused, very dense clinker is environmentally stable and can be shipped around the world in bulk without concern for degradation. One site for grinding this clinker into cement is here in Chesapeake, VA where we grind FONDU cement to 4,000 cm2/g Blaine surface area.
