Original Abstract

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

Keywords
