| 摘要 | The corrosion resistance performance of the rebar quenched by a new chemical reagent FM in concrete containing chloride ions was evaluated comparing with bare rebar, water-cooled rebar and air-cooled rebar using electrochemical methods. Two different accelerated corrosion tests (14 cycles of dry/wet alternated corrosion tests and long-term immersion tests) were carried out to accelerate the corrosion process. EIS results of both accelerated corrosion tests showed the corrosion resistance performance of different rebar specimens could be sequenced from high to low as FM-cooled rebar, bare rebar, air-cooled rebar, and water-cooled rebar. It was observed that, after 14 cycles of accelerated corrosion tests, the corrosion degree of FM-cooled rebar is the slightest and most of the initial scale remains undamaged. This result proves that the corrosion resistance of the FM-cooled rebar is much better than the other three kinds of rebar. By using FM-cooling process, the corrosion resistance performance of rebar in concrete has been improved by optimizing the quality of the scale. (C) 2010 Elsevier Ltd. All rights reserved. |
