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.

蒸気養生により再水和が施される。The glazed concrete panel can be obtained by drying the concrete panel thus obtained at about 250 to 350 ° C for about 5 hours, then glazing it, and then firing at about 800 to 900 ° C for about 1 hour. . The concrete panel after firing is rehydrated by immersion in water and steam curing as needed to improve strength.

する点に特徴がある。The repair method of the present invention is characterized in that after the defective portion of the concrete panel is glazed, the defective portion is filled with mortar, and then the entire panel is dried, glazed and fired according to a usual method.
欠損部に塗布される釉薬は、乾燥後にパネル全体に塗布
されるものと同一であってもよいし、別であってもよ
い。具体的には、フリット釉、生釉などを用いることが
できる。The glaze applied to the defective portion may be the same as that applied to the entire panel after drying, or may be different. Specifically, frit glaze, raw glaze, etc. can be used.
欠損部への釉薬の塗布は、スプレーなどにより行なうこ
とができる。The glaze can be applied to the defective portion by spraying or the like.
