Abstract
A different material from concrete, mortar, attachment mortar, and a tile adjoins mutually, and finish of the tile on the surface of concrete is constituted. The time of adding load to concrete between the inside of each material, and material tensile stress and shearing stress which is not carried out occurring, and neither material nor its adhesive strength being able to bear these by repetition of the action, but resulting in exfoliation. It aims at preparation of the ground processing method that a tile does not exfoliate easily to shear failure which is produced shockingly in an instant and which is not carried out, and mortar mixture, mortar applying to concrete surface, and thickness of coating etc in this research.
