Development of Reuse Method of Ceramic Tile.

Part1. Method for Removing Mortar Using Acid from Tile and Adhesive Property of Tile Dipped Acid

Abstract

In repair work and rebuilding construction,sometime it is demanded that we suggest the reconstruction or preservation of exterior tile.About tile for reuse,there are some tasks to remove mortar efficiently which adhered to a surface of tile.For such demands,the authors developed the reuse method using the acid.In this paper, we conducted three experiments,(1)the condition of acid which remove mortar efficiently,(2)analysis of the salt remains on tile dipped acid,(3)adhesive property of tile attached to this salt.As a result,we decided to use the hydrochloric acid for a development method.The tile dipped acid have a negative influence on the adhesive property,so it was provided the washing process after a mortar removal process.
