FIRE-RESISTANT HEAT INSULATION COMPOSITION, FIRE-RESISTANT HEAT INSULATION COMPOSITION SLURRY, FIRE-RESISTANT HEAT INSULATION BOARD, AND FIRE-RESISTANT HEAT INSULATION STRUCTURE

摘要

Provided is a fire-resistant heat insulation composition whereby it is possible to achieve suitable heat insulation properties and fire resistance.　The fire-resistant heat insulation composition includes: 5-100 parts by mass of gypsum with respect to 100 parts by mass of calcium sulfoaluminate including at least 40-70 mass% of hauyne and 5-30 mass% of belite; and 0.1-20 parts by mass of a fibrous inorganic clay mineral with a moisture content of at least 5% with respect to a total of 100 parts by mass of the calcium sulfoaluminate and the gypsum.
