PROBLEM TO BE SOLVED: To provide a structure for preventing an explosive fracture of concrete, which is excellent in its shape retentivity even if it is exposed to a high temperature for a long period of time, and its construction method. SOLUTION: This structure for preventing the explosive fracture of the concrete is characterized as follows: a surface of a concrete structure is coated with a thermally-expansible inorganic material; the thermally-expansible inorganic material consists of 55-85 wt.% inorganic fibers, a 5-30 wt.% thermally-expansible inorganic substance, a 5-25 wt.% inorganic binder, and a 5-15 wt.% organic binder; and the inorganic binder, which is contained in the thermally-expansible inorganic material, consists of a sinterable inorganic material with a melting point of 650-1,000°C.
