The present invention relates to a refractory repairing method for a concrete structure using a high strength polymer mortar and a refractory mortar, and more particularly, to a refractory mortar composition which can be easily applied to a surface or a cross section of a concrete structure by spraying, It is a construction method to repair the deteriorated parts. It has high strength performance and excellent fire resistance. It is suitable for repairing in poor environments, has excellent durability, has small amount of rebound, and has excellent properties such as compressive strength and bending strength. And to provide a refractory repair construction method of a concrete structure that can prevent a problem caused by heat radiation. |
