The given paper analyses the effect of FFFS on both, safety of users and structural safety based on results from the SOLIT2 project. Within the scope of the SOLlT2 project, the efficiency of water mist fire fighting systems in...

Practical Application of a Cement-free Shotcrete for Tunnel Refurbishment
Abstract: Existing road and railway tunnels in Central Europe increasingly show signs of aging and deterioration, which is particularly evident in the tunnels’ inner lining. Due to dramatic tunnel fires, and novel research findings, German authorities have reviewed and revised several guidelines for the design of tunnel structures in recent years. In the national research project KOINOR, a cement-free...
