<p>PURPOSE: An adhesive composition for a curtain wall fire resistance light weight board is provided to attach the fire resistance light weight board or a fire resistance ultra-light weight foamed board to an aluminum curtain wall by containing cement, blast furnace slag, fly ash, an alkali silicate solution, lightweight fine particles, and a thickening agent as light weight inorganic adhesive components. CONSTITUTION: An adhesive composition for a curtain wall fire resistance light weight board contains: 100 parts by weight of mixture containing 10-40 parts by weight of cement, 10-40 parts by weight of blast furnace slag fine powder, 10-40 parts by weight of fly ash, and 25-70 parts by weight alkali silicate solution; 10-50 parts by weight of light weight fine powder; and 0.015-5.0 parts by weight of thickening agent. The average particle size of the light weight fine powder is less than 5 mm. The light weight fine powder is fine powder of one material selected from a group consisting of waste glass foamed boards, waste light weight foamed concrete, bottom ash, a light weight mixture, or a mixture thereof. A constitution method of an aluminum curtain wall comprises the following steps: attaching a metal lath and a perforated plate on the outside of the aluminum curtain wall; installing a joint metal portion (23) on the rear side of the aluminum curtain wall; coating the adhesive composition on the joint metal portion or the rear surface of the aluminum curtain wall; and attaching the fire resistance light weight board (11) or a light weight inorganic foamed board.
