Development of a highly ductile sprayed concrete as a counter-measure for explosion and fire impacts on underground...
Abstract: Extreme impact, as it may result from scenarios like explosions or huge fires, has to be considered as a valid scenario especially when dealing with objects of our urban infrastructure. Currently there is only limited amount of countermeasures available with most of them being developed for one specific threat – fire or explosion. Thus differing impact might expose weaknesses of the measure...

KOINOR - Development of a Sprayable Geopolymer Concrete for Fire Protection Improvement and Upgrading of Underground...
Abstract: The existing tunnel structures in Germany are characterised by progressive ageing, which is particularly evident in the tunnels’ inner lining. In addition, under the influence of incisive events and new research results over several years, the government has reviewed and updated some of the guidelines under which these buildings were designed and constructed.

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...

U-THREAT - Underground Transport Hub Resilience to Ensure
Abstract: To face important traffic issues, large cities and metropolitan areas rely on the metro networks as the backbone of citizens’ mobility. Although underground transport is gaining popularity, it is also exposed to diverse threats, such as fires, explosion or technical failure, which can lead to great impairments. In the U-THREAT project, the first objective is to identify the possible terroristic...
