酸を用いるセラミックタイルの再利用工法の開発

Tiles used inside and outside of buildings with high cultural or historical value are required to be reused. We have developed a method to reuse those used tiles using acid. In this method, we remove mortar from the tiles by dissolving mortar itself with acid. In this paper we report the results of the tests conducted for two purposes. The first purpose was to find particular conditions of acid that can dissolve mortar quickly. The second purpose was to ensure the adhesion quality of the reused tiles.
