An Experimental Study on Monitoring the Filling Status of Concrete in Thick Wall with Steel Plates on the Outside using Infrared Cameras

This paper presents an experimental study using test specimens to demon-strate that the filling status of concrete on the inner surface ofathick wall’s steel platescan be monitored on the outside using infrared cameras. In previous research, it wasfeasible to monitor the filling statusof concrete onthewallwith a steel plate thickness of10mmor lesson the outside using infrared camera.In this study, the steelplate thick-ness is increased from10mm to 22 mm and 32 mm.
