Corrosion of reinforcing bars in concrete structures influences lifespan negatively and makes losses. In order to make longer lifespan and prevent losses, a qualitative measurement technique which can measure the extent of corrosion of reinforcing bar need to be developed. The purpose of this study is to develope technique to measure corrosion of reinforcing bars using infrared thermal photography graphic data. The result of experimental study shows that a test body emits stronger infrared thermal distribution on concrete surface which contains relatively more corroded reinforcing bar.

Corrosion of reinforcing bars embedded in concrete structures influences lifespan negatively and makes losses. In order to make longer lifespan and prevent losses, a qualitative measurement technique which can measure the corrosion level of reinforcing bar need to be developed. The purpose of this study is to develope the technique to measure the corrosion of reinforcing bars using infrared thermal photography graphic data. The result of experimental study shows that a test body emits stronger infrared thermal distribution on concrete surface which contains relatively more corroded reinforcing bar. Based on the infrared thermography database which constructed by the atmosphere temperature and concrete cover depth and many other test parameters, a qualitative corrosion evaluation can be made by comparing laboratory test results and the real site test results.

In the current study, retarding type and standard type admixture design of concrete have been proposed to control the generation of hydration heat for foundation members that use high strengths concrete. Finite element analysis also has been conducted to understand the rational placing heights of concrete. In addition, real-size structures have experimented and their results were compared to the analytical results to evaluate the reducing effect of thermal stress . For a large 6.5 m×6.5 m×3.5 m member with retarding and standard type horizontal partition placement of concrete showed the manageable possibility of temperature difference within 25-degree Celcius between the middle and surface portion while the maximum temperature was 77-degree Celcius. Also, temperature cracking index from the finite element analysis appeared to be 1.49 that predicts no formation of cracking due to the effects of temperature. Finally, it appeared that horizontal partition placement of retarding and standard type concrete has the significant effect of reducing the thermal stress that generated by the hydration heat in the high strengths mass concrete.

In recently, the method estimated construction's defeat using the infrared thermography was prefer to method of new repair and estimate as a good point that simple of application and save labor, what is more economic than other techniques and can reduce need time. The purpose of this study is to develope the technique to measure the corrosion of reinforcing bars using the infrared thermal photography graphic data. In this page, the former final purpose establishment that galvanic corrosion method of reinforced bars and infrared thermography system, and studied trend of thermography and photography graphic data by parameters of corrosion of specimens, atmosphere temperature, concrete cover depth etc.
