Original Abstract

Concrete structures are also commonly exposed to thermal loads as the result of the structure, ambient conditions, the heat of hydration, or exposure to fire. Therefore, there has been a growing interest in research on the advanced monitoring and analysis of concrete structures subjected to thermal load. The non-linear characteristics have been used to identify thermal damage evolution in concrete structures. This paper presents the effects of a high temperature on selected physical properties of concrete. Concrete properties were monitored and analyzed loaded in a few thermal steps up to 1200 °C. Therefore, the concrete specimens were heated in a programmable laboratory furnace at a heating rate of 5 °C/min. The specimens were loaded at six temperatures, i.e.,200 °C, 400 °C, 600 °C, 800 °C, 1000 °C and 1200 °C maintained for 60 minutes.
