Evaluation of Durabilities in Ruined RC Bridge
철근콘크리트 철거교량의 내구성 평가
Abstract
An experimental investigation on the ruined RC bridge with 30 years old has been conducted to estimate the durabilities. The ruined RC bridge estimated in this study was located at Kyung-Bu Express Way. First, concrete strength and durability characteristics such as concrete resistivity, chloride content were estimated. Second, it was to test reinforcing corrosion embedded in slab of bridge. And, third, tensile strength and yield strength of reinforcing bar corroded and not corroded were estimated. This bridge inspection provides the most common cause of defects and deterioration and the results of this inspections give more specific information than those of laboratory inspections do.
