    Abstract
  • Aiming at the low brine corrosion resistance of ordinary silicate reinforced concrete in salt lake areas of western China, a magnesium oxychloride cement reinforced concrete with higher brine corrosion resistance was fabricated. The polarization curves and electrochemical parameters, including corrosion potential, corrosion current density and corrosion rate, of steel bars with different coatings were investigated in magnesium sulfate solution using an electrochemical workstation measurement system, and the corrosion and protection of steel reinforcements in the chloride magnesium cement concrete with high chloride content were studied. The results show that the bare steel bar in the magnesium oxychloride cement concrete suffered severe corrosion, the steel bars with DACROMET, BENICE, ZINTEK and MAGNI coatings presented low corrosion, and the steel bar with GEOMET coating was far from corrosion. Specifically, the corrosion rate of steel bars with coatings of DACROMET, BENICE, ZINTEK, MAGNI and GEOMET was 1/36-1/19, 1/20-1/13, 1/31-1/16 and 1/91-1/50, respectively, while the value was 1/22-1/16 for the bare steel bar. This proves that coating technology can slow down the corrosion rate of steel bars in magnesium cement concrete.
