PROBLEM TO BE SOLVED: To provide a wall strengthened in adhesion to mortar, in which the adhesion of mortar to the substrate is enhanced in a positive manner. SOLUTION: A framework 4 on whose inner surface an adhesion-strengthening agent 5 for concrete and the like, obtained by mixing a fiber-reinforcing material 3 of cement-based hardening material and a water-soluble or alkali-soluble adhesive or an adhesive being decomposed with an alkali, has been coated or laminated is used, and concrete 1 is charged in the framework 4, solidified, and cured. Then, the framework is detached. The fiber-reinforcing material 3 is hair-planted in the concrete in such a manner that the one side of the fiber is taken in the concrete and the other end is exposed. The adhesion of mortar to the concrete can be strengthened by coating the mortar 2 on the surface of such concrete. The wall strengthened in adhesion to mortar is useful for mortar inner and outer walls, a ceiling or a floor surface of a concrete building structure. COPYRIGHT: (C)2003,JPO
