The method of making cement from limestone (CaCO 3) and low-silica bauxite (Al 2 O 3) 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" and "Ciment électro-fondu" in French. [2] [3]
Fondu Fyre, sometimes called Fondue Fyre, is a refractory concrete developed for specialist application. Fondu Fyre is a heat and erosion resistant concrete developed during the Apollo space program. It was developed to withstand the supersonic plume of a rocket engine during launch and hot-fire tests [citation needed].
It is a type of calcium aluminate cement used for constructing moulds or outdoor works. Typically Ciment Fondu needs to be used as a composite material reinforced with fibre glass, building up the mould in series of layers. Fast setting, it achieves its full strength in 24 hours.
Concrete is sometimes used as a fire protection for steel frames, for the same effect as above. Concrete as a fire shield, for example Fondu fyre, can also be used in extreme environments like a missile launch pad. Options for non-combustible construction include floors, ceilings and roofs made of cast-in-place and hollow-core precast concrete.
