چکیده انگلیسی
The durability of concrete structures decreases easily due to such environmental effects. For effective maintenance of concrete structures, it is necessary to evaluate not only the values of mechanical properties but also the degree of damage. In this study, damage estimation of concrete is proposed to be performed, applying AE and X-ray CT. Testing concrete core samples were taken from reinforced concrete columns of an existing canal, which is strongly affected by freeze and thawed process. Thus, a relation between AE and X-ray CT parameters is correlated, and the damage of concrete is quantitatively estimated using AE and X-ray CT.
