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

  • The fire-induced spalling behaviour of concretes has a huge effect on the fire resistance of concrete components. Therefore, fire performance must be taken into account in the design and dimensioning of concrete structures. The use of new types of concrete and different types of cement or binder must also be considered. Despite decades of research, the mechanisms underlying the spalling phenomenon are not yet fully understood. However, knowledge about these mechanisms is the prerequisite for predicting the spalling behaviour as accurately as possible. 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 regarded. Against this background, the effect of avoidance strategies can be evaluated.

Thereby, a variety of influencing parameters must be regarded. 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 researchers and practitioners, exchange the latest research results and newly acquired data from real fire scenarios, and discuss current developments in the field of concrete spalling. After the successful workshops in Leipzig (Germany), Delft (Netherlands), Paris (France), Borås (Sweden) and Sheffield (United Kingdom), the 7th International Workshop IWCS took place in Berlin at BAM. It provided insights into the work of two RILEM Technical Committees. Based on this, various results of screening tests and large-scale tests for the assessment of the fire-induced spalling behaviour of concretes were presented, taking into account a large number of influencing parameters. Further topics of the workshop were the analysis of the mechanisms for the spalling phenomenon as well as the modelling and simulation of the spalling processes. A large part of the workshop was devoted to the high-temperature behaviour of various types of concrete. The workshop was dedicated to Prof. Diederichs, who passed away on 20 January 2022. With his death, the spalling community lost an internationally renowned expert in the field of fire behaviour of concrete and reinforced concrete components. He played a decisive role in the design of all previous RILEM TCs on the high temperature and fire behaviour of concretes and reinforced concrete components.zeige mehrzeige weniger
