철근부식정도가 철근의 역학적 특성에 미치는 영향

This paper reports results of a study conducted to assess the effect of degree of corrosion of reinforcing steel bar on their mechanical properties. Reinforcing steel bars, 13mm in diameter, that were corroded by electrically accelerated corrosion method in concrete specimens were removed and tested in tension. Results indicated that the level of reinforcement corrosion influenced yield point, the tensile strength and elongation of steel bars.
