7th international workshop on concrete spalling due to fire exposure - Proceedings

The spalling behaviour of fire exposed concrete has a huge effect on the fire resistance of concrete components. During the designing process of modern concrete structures, the fire performance must be considered. Thereby, the comprehension of the spalling phenomenon and the underlying mechanisms helps to predict the spalling behaviour of concrete components.

Experimental research from material characterisation on the micro scale up to full-sized fire tests as well as the simulation and modelling of fire-induced damage processes offer the opportunity to investigate the spalling behaviour of concrete. Thereby, a variety of influencing parameters must be taken into account. Against this background, the effect of avoidance strategies can be evaluated.

Since 2009 the International Workshop on Concrete Spalling due to Fire Exposure (IWCS) offers a platform to get in touch with other researchers, share latest research achievements and new gained data of real fire scenarios and discuss the current developments in the field of concrete spalling. After the successful workshops in Leipzig (Germany), Paris (France), Borås (Sweden) and Sheffield (UK), the next IWCS will take place in Berlin at BAM. This workshop will also pay tribute to the memory of Prof. Dr.-Ing. Ulrich Diederichs, who passed away in 2022. Due to the pandemic situation, the IWCS 2021 has been postponed. We look forward to welcoming you at the 7th IWCS for 2022 at BAM in Berlin.
