Proceedings pro080 : 2nd International Workshop on Concrete Spalling due to Fire Exposure
Title: 2nd International Workshop on Concrete Spalling due to Fire Exposure Edited by E.A.B. Koenders and F. Dehn ISBN: 978-2-35158-118-6 e-ISBN: 978-2-35158-119-3 Pages: 453 Publication date: 2011 |
Controlling the sensitivity of concrete to its (explosive) spalling behaviour during fire exposure is one of today's major issues in the design and construction of concrete structures. Fires - such as the Channel tunnel fire - indicated that spalling of concrete can have serious structural and economical consequences and is a phenomenon that should be taken into account when designing for fire.
Developments in concrete mix design have lead to new types of concrete - such as high strength, ultra-high strength and self--compacting concrete - which, besides an increased structural performance, also have shown a different sensitivity to spalling due to fire exposure. However, until now the sensitivity of a concrete as a material and for structures to spalling is not fully understood. More research is needed to understand the mechanisms behind spalling in order to be able to quantify the risk of spalling.
This workshop focuses on spalling of concrete due to fire exposure and emphasizes real life experiences and observations, practical applications and developments in experimental testing, and numerical modelling. The aim of this workshop is to obtain an overview of the state of the art level of knowledge, to exchange results and to stimulate the discussion between researches and representatives from the industry.
