PURPOSE: A sealing material is provided to effectively block the contact with air and to reduce work load by improving processability and disassembling ability. CONSTITUTION: A sealing material includes a packing material and a wet inorganic material which fills the packing material. The inorganic material comprises Al2O3 and SiO2. The packing material comprises 5-30weight% of Al2O3 and 50-80weight% of SiO2. The inorganic material consists of 15-35weight% of aggregate with a particle size of 1.6mm or more, 30-50weight% of micropowder with a particle size of 0.3mm or less, and middle size particles with a particle size of 0.3-1.6mm.
