| v| | In this paper, the intermediate products, including aka-ganeite (ภ-FeOOH) and lepidocrocite (ม-FeOOH), and the final products, including hematite (ฟ-Fe 2 O 3 ), maghemite (ม-Fe 2 O 3 ) and goethite (ฟ-FeOOH), of steel corrosion in seawater & sea sand-based concrete under different environments were investigated by the XRD and SEM. In the seawater immersion-dry repeating environment, the ฟ-FeOOH, ฟ-Fe 2 O 3 and magnetite (Fe 3 O 4 ) converted mutually. Also, in the seawater environment, the ม-FeOOH and ภ-FeOOH substituted for oxygen as the new depolarizers of cathode reduction reaction. |
