A Study of Non-destructive Measurement on the Reinforced Concrete Structure Damaged by Reinforcing Steel Corrosion

철근콘크리트구조물의 철근부식에 대한 비파괴 측정과 부식에 따른 균열거동

This experimental study was performed to derive the relationship between the measured values(corrosion potential) and the actual amount of corrosion products(reinforcing steel weight loss rate). Also the growth of crack due to the steel corrosion was oberved. First, the reinforcing steel of R/C specimen was corroded with chloride penetration and accelerated galvanostatic corrosion method. And then, the corrosion potential of reinforcing steel was measured with nondestructive tester.
