剥離してしまい、現実に補修方法として採用することが
できない。By the way, in the concrete panel after molding and curing, a defective portion of the concrete, that is, a so-called chip may be generated due to poor casting, poor compaction or impact during handling. Not only is this defective portion unfavorable in appearance, but it also reduces the strength and durability of the concrete, so it needs to be repaired. As a correction method, it is possible to fill mortar before glazing and firing, but when firing with mortar filling, the repaired part will be insufficiently attached and easily peeled off, and it is actually used as a repair method Can not do it.
そこで、欠損部があるままでコンクリートパネルに施釉
し、焼成したのちに欠損部にポリマーセメントを充填
し、充填部に有機塗料を塗布するという補修方法がとら
れている。Therefore, a repairing method has been adopted in which a concrete panel is glazed with a defective portion left, and after firing, the defective portion is filled with polymer cement and an organic paint is applied to the filled portion.

題がある。However, even with the above method of polymer cement filling,
There is a problem that the glaze treatment part and the repair part have different weather resistances, the repair part deteriorates quickly, and the textures of the glaze treatment part and the repair part are different.

供することである。The present invention has been made in view of the above circumstances, and an object thereof is to provide a repairing method in which the drawbacks of the conventional example are eliminated. That is, an object of the present invention is to provide a method for repairing a glazed concrete panel, which is capable of unifying the textures of the glaze treatment part and the repair part without causing the repair part to peel off or deteriorate quickly.

薬とセメント、骨材などが混練される。The glaze mixed in the mortar may be the same as or different from the one applied to the concrete panel after drying. Specifically, frit glaze, raw glaze, etc. can be used. When actually producing a glaze-containing mortar, for example, frit, clay, CMC and water are ground by a wet mill for about 2 hours, dried and then granulated into a granular glaze, cement, aggregate and the like are kneaded.

にして補修部の付着力を測定した。With respect to the obtained glazed concrete panel, the adhesive force of the repaired portion was measured in the same manner as in the example.
結果を第１表に示す。The results are shown in Table 1.
参考のために補修部以外の施釉コンクリートパネルの付
着力を測定した。結果を第１表に示す。For reference, the adhesive force of the glazed concrete panel other than the repaired part was measured. The results are shown in Table 1.

向上させるためである。 As is clear from Table 1, the repaired portion of the mortar mixed with the glaze had a markedly improved adhesive force as compared with the mortar not mixed with the glaze, and the adhesiveness was similar to that of the portion other than the repaired portion. This is because the glaze previously mixed in the mortar is melted by firing and the adhesion of the cement particles is improved.

効果を奏することができる。[Effect of the Invention] As described above, according to the method for repairing a glazed concrete panel of the present invention, the glaze is mixed in the repair mortar, and the glaze melts during firing to improve the adhesion of the cement particles. Therefore, the repaired part does not peel off,
Further, it is not necessary to repair the polymer cement or the organic paint after firing, and it is possible to prevent the repaired part from being deteriorated quickly and to make the textures of the glaze processing part and the repaired part uniform.
