چکیده انگلیسی
The effect of medium temperature on the transport properties of concrete was investigated. The transport properties, the non-steady-state migration coefficient and the steady-state migration coefficient, were investigated after the specimens were heated to the temperature of 95 °C. In this study the electrochemical technique was applied to accelerate chloride ion migration in concrete to estimate the breakthrough time and the chloride flux. The non-steady-state chloride migration coefficient and the steady-state chloride migration coefficient of concrete were calculated from the modified Fick's second law based on measurements of the breakthrough time and the chloride flux. The results show that the non-steady-state migration coefficient and the steady-state migration coefficient increase by 4.6-14.6 times and by 2.3-7.1 times, respectively, when the temperature is raised from room temperature to 95 °C.
