- Abstract
- 공용년수 40년 이상의 실제 교량에서 시편을 채취하여 해당 교량의 동결융해 저항성에 대한 시험을 수행하였다. 분석결과, 대다수의 시편에서 박리(scaling) 현상이 나타났으며 이를 통해 동결융해 저항 성이 현저히 떨어지는 것을 확인하였다.
In order to perform the freeze-thaw resistance of concrete bridge, specimens were collected from a bridge in service life of 40 years. As a result of the analysis, most of the specimens showed a scaling in the surface layer, it was confirmed that the resistance was low both scaling and freeze-thaw resistance.
