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.
