The influence of aggregate grain size on the parameters of acoustic emission signals obtained from a three-point bending test on concrete specimens degraded by high-temperatures
Original language description
This paper presents the measurement results of a three-point bending test on three different mixtures of concrete specimens that have been exposed to high temperatures. The concrete specimens were heated in a programmable laboratory oven at a heating rate of 5 °C/min and were exposed to the following temperatures: 400 °C, 600 °C, 800 °C, 1000 °C and 1200 °C. The heating was maintained for 60 minutes. The obtained results indicate that the comparison of the absolute measured values is not sufficient. For this reason, the comparison of the individual mixtures is carried out using the relative values, which more clearly demonstrate the degree of damage to the concrete samples caused by exposure to elevated temperatures.
