Abstract: An inorganic fire-proof coating material can form a coat film to be transformed into a foamed layer demonstrating quite superior heat insulation ability by uniform foaming as subject to heat, such as that upon fire to prevent softening of the steel material coated by the coat film for a long period to be sufficiently practically applicable as a fire-proofing coat for steel frame structure or the like, and an inorganic fire-proof structure formed by coating the fire-proof coating material. The fire-proof coating material is consisted of an aqueous paste containing water soluble alkaline silicate in a content greater than or equal to 30 Wt % in components excluding water, holmite series mineral powder, and SiO2 supplying components other than water soluble alkaline silicate and holmite series mineral.
