Fire resistance of lightweight constructions made of carbon concrete composites

The project focuses on lightweight constructions made of textile-reinforced concrete. The mechanical properties at ambient and elevated temperatures are analysed, and a proposal for structural fire design and the fire resistance assessment will be developed. The material combines the advantages of high-performance concrete and non-corrosive carbon reinforcement. Thus, the cross-section of elements can be minimised, associated with reduced used materials and less environmental impact. The saving of natural resources and climate protection are the main challenges for the future of the building construction industry.

This international project combines the manufacturing and structural design expertise of CTU UCEEB and BAM knowledge about fire testing and high temperature material optimisation. Currently, the use of TRC is limited to applications at ambient temperature because several questions concerning the fire resistance of structural TRC elements need to be answered: e.g. faster heating of the cross section, spalling of HPC and temperature related degradation of the textile reinforcement.

This international project is implemented in cooperation with the Bundesanstalt für Materialforschung und –prüfung (BAM), Berlin, Germany, with financial support from the Grant Agency of the Czech Republic and the German Research Foundation.
