PCT No. PCT/BE95/00010 Sec. 371 Date Aug. 23, 1996 Sec. 102(e) Date Aug. 23, 1996 PCT Filed Feb. 3, 1995 PCT Pub. No. WO95/23199 PCT Pub. Date Aug. 31, 1995A method for repairing industrial facilities at high temperatures using at least one prefabricated element made of a -mullite-crystallized refractory product with an alumina content of 30-85%, preferably 50-80%, made of refractory materials securely attached to the structure of the facility by using an oxygen containing carrier gas stream to spray a mixture of particles capable of exothermically reacting with the oxygen and particles of a refractory material, whereby a coherent refractory mass is formed in situ for attaching said element to said structure.
