An asbestos-treating agent and a process for treating asbestos are disclosed. The treating agent contains one or more acids selected from among mineral acids containing at least one element of phosphorus, sulfur, nitrogen and halogen and an aqueous inorganic high-molecular compound as major components. The process for treating asbestos comprises coating or spraying the surface of an asbestos-containing structure or asbestos wastes with the asbestos-treating agent to react with needle-like asbestos to thereby solidify them as a massive product. The process enables various asbestos-containing structures or asbestos wastes derived from them to be solidified and modified into a harmless substance. La présente invention décrit un agent et un procédé de traitement d'amiante. L'agent de traitement contient un ou plusieurs acides choisis parmi des acides minéraux contenant comme composants principaux au moins un élément de phosphore, de soufre, d'azote et d'halogène et un composé inorganique aqueux à poids moléculaire élevé. Le procédé de traitement d'amiante consiste à enduire ou à vaporiser la surface d'une structure contenant de l'amiante ou des déchets d'amiante avec l'agent de traitement d'amiante pour que celui-ci entre en réaction avec l'amiante aciculaire, la structure ou les déchets ainsi traités se solidifiant alors sous la forme d'un produit massif. Ledit procédé permet la solidification et la modification en une substance inoffensive de diverses structures contenant de l'amiante ou de déchets d'amiante provenant de telles structures.
