Experimental Study On Thermograph Method For External Wall Removement Finished With Ceramic Tile

摘要

The author experimented to make the following relation clear about the external wall which is finished with the tile, the kind of tile, the condition of the removement, the environment at taking a thermograph, the wavelength of thermo-camera and the characteristic of the thermographs and the precision to distinguish removed parts. By the experiments using the test walls, the following item became clear. (1)the removement of tiles and the removement of fundamental mortar differ in the temperature response speed to the change of solar radiation. (2)As for the walls without solar radiation, it is possible to apply the thermography method, but it is rather unclear. (3)When the solar radiation lashes to the wall, as dark as the color of tile, it is easier to distinguish the removed part.
