Abstract
The outdoor exposure test for ten years was usually carried out about the examination object produced by the after [ a ceramic tile ] tension method of construction to concrete. Examination levels are the curing period after concrete placing, the surface treatment of concrete, the kind of mortar setting beds, and tiling method. Consequently, the concrete surface treatment by the mortar concrete rivet-back method and the high-pressure water washing method has verified that ten years or more of exfoliation prevention was maintainable. Moreover, the thing which, as for construction of direct tension, generating of exfoliation is accepted in a plywood side, and a problem is in durability when on-site preparation mortar is used as tile ground mortar has usually been checked.
