摘要: As a fundamental study on the performance of Cr-bearing rebars in steel reinforced concrete structures exposed to corrosive environments, The test specimens were made by installing 8 types concretes with chloride ion content 0.3, 0.6, 1.2, 2.4 and 24 kg/m3. Corrosion accelerated curing then conducted them. corrosion resistance was examined measuring crack widths, half-cell potential, area weight loss after 155 cycles corrosion- accelerating curing.The results showed that increased as Cr regardless ions, 5% 9% high 1.2 kg/m3, respectively.
