Description of the research topic:
Recent fire cases in tunnels and in skyscrapers indicated again the importance of fire research. Initiation and development of fire are strongly influenced by the applied construction materials. In addition to their mechanical properties, their behaviour in elevated temperature is also of high importance.
The most important construction material is concrete and reinforced concrete. Residual compressive strength of concrete exposed to high temperatures is influenced by the following factors water to cement ratio, cement to aggregate ratio, type of aggregate, water content of concrete before exposing it to high temperatures and the fire process.
The behaviour of concrete has an influence on the loadbearing capacity of structural elements. The aim of this resarch is to indicate ranges of influences, with laboratory methodes and modelling.
