PCT No. PCT/EP92/01826 Sec. 371 Date Jun. 2, 1994 Sec. 102(e) Date Jun. 2, 1994 PCT Filed Aug. 12, 1992 PCT Pub. No. WO93/04010 PCT Pub. Date Mar. 4, 1993.The invention relates to a furnace having an inner wall, an outer wall and a heat insulation arranged in between. The heat insulation is foamed up in situ, and hardened, from a mass which contains, per 100 parts by weight of a reactive solid (stone-forming component), 40-250 parts by weight of a water-containing hardener which effects the hardening reaction of the reactive solid (stone-forming component) in the alkaline region, 40-250 parts by weight of fillers and a blowing agent. The reactive solid used is preferably a reactive solid from the group comprising I finely dispersed oxide mixture containing amorphous silica and alumina, II a glassy, amorphous electrostatic precipitator ash, III ground calcined bauxite, IV electrostatic precipitator ash from lignite-fired power stations, V undissolved, amorphous SiO2, especially from an amorphous, disperse-pulverulent, dehydrated or water-containing silica or from high-temperature processes (silica fume), and VI metakaolin.
