Evaluation of acoustic emission signals obtained during the three-point bending loading of thermally degraded concrete samples
Original language description
Due to fires of building structures, there has been a growing interest in investigating the properties of concrete at high temperatures. In a fire, a temperature of up to 1400 °C may be measured. Such high temperatures will cause changes in the structures of the entire construction. Ultrasonic methods such as acoustic emission method can be used to monitor changes in the structure caused by a fire. Heated to selected temperatures of 200 °C, 400 °C, 600 °C, 800 °C, 1000 °C, and 1200 °C, the concrete specimens were maintained for 60 minutes. Then, they were dried for another 48 hours at 110 °C and, after that, cooled down to a laboratory temperature. Beam concrete specimens were loaded under a three-point bending test. The evaluations of the experiments imply the possibility of using the acoustic emission method to describe the changes in a concrete structure after it is fire-degraded at the three-point bending loading.
