The Study on the rebar corrosion by NaCl solution through the infrared camera

  In order to measure the extent of corrosion of rebar in the concrete, infrared thermography method was applied. The concrete was corroded in the 3 % NaCl solution. To get the difference of temperature of the concrete, surface heating was adopted. According to the extent of corrosion, peak temperature comparing to around position was formed. This is the reason that the crack of concrete formed by corrosion affected the decrease of temperature. This result shows that using the data accumulated, the extent of corrosion of rebar can be measured by infrared thermography method.
