Abstract: A compilation of fire test data has shown distinct behavioral differences between high performance concrete and traditional concrete at elevated temperature. The differences in fire behaviour are largely depending on the microstructural properties, especially on the porosity, pore size distribution and the connectivity of pores. Self-compacting concrete, as a new smart building material with varies advanced properties, has been used for a wide range of structures and infrastructures. However the microstructure changes of self-compacting concrete at elevated temperature are not investigated.
In this contribution, the microstructure changes of self-compacting concrete at elevated temperature are examined by mercury intrusion porosimetry and scanning electron microscopy. The chemical de-composition of self-compacting concrete at different temperatures is determined by thermogravimetric analysis. The experimental results of self-compacting concrete are compared with high performance concrete and traditional concrete.
