PURPOSE: An inorganic anti-dusting agent for asbestos is provided to ensure excellent fire refractoriness and heat resistance while not containing volatile organic chemicals, high solidifying property with asbestos, and excellent bond to asbestos. CONSTITUTION: An inorganic anti-dusting agent for asbestos comprises an inorganic binder of an aluminosilicate skeleton, an aminoalkyltrialkoxysilane coupling agent, and water. Or the inorganic anti-dusting agent for asbestos comprises a reaction product bonded to silicon atoms of the coupling agent through oxygen atoms to aluminum atoms of the inorganic binder as a reaction product obtained by reacting the inorganic binder and the coupling agent in the presence of water. The inorganic anti-dusting agent for asbestos does not have volatile organic compounds with the proviso that the aminoalkyl group of the coupling agent is connected to the silicon atom by an Si-C bond and at least one amino group is positioned at the end of the aminoalkyl group opposite to carbon bonded to silicon atom.
