摘要：
This paper deals with the fire resistance of repaired components by polymer-modified cement mortar. The experiment examine fire test for two hours, confirmed the damage conditions and the temperature distribution of repair sections, and adhesive strength. As the result, the monolithic property of repair section depends on its size and thickness, the case of large and thin is relatively danger. The temperature distribution in the repair section is relatively low compared with an ordinary concrete and mortar, so harmful influence to the structural safety in fire is low from the viewpoint of the temperature of the reinforcing bar.
