초록
In the construction site, various crack repair methods were used on concrete structures. Especially, the epoxy injection methodwas used on the economics, however various problems such as difficulty of material injection under the high pressureconditions, lacks of material injection under the low pressure conditions, and materials separation under the high pressureconditions were occurred. Therefore, there were conducted Mock-up Test and actual application using T-Port at on-site, andinvestigated the effect of injection on the concrete structure. Moreover, the ultrasonic test was also conducted in order toevaluate before and after repair effects. From there results, it was founded that T-port had a good performance for the crackinjection compared to traditional method.
