Detection of Concrete Cover of Reinforcements in Reinforced Concrete Wall by Microwave Thermography with Transmission Approach

Autor: Sam Ang Keo, Franck Brachelet, Didier Defer, Florin Breaban

Publikováno v: Applied Sciences, Vol 12, Iss 19, p 9865 (2022)

Concrete cover has an important role in reinforced concrete (RC) structures because it protects reinforcement bars from the bad effects of weather, fire, and bad environmental conditions that cause the corrosion of the reinforcements. Although it is
