Spalling of Concrete due to Fire Exposure

This book presents the work of RILEM TC 256-SPF, and provides a comprehensive review of concrete spalling under fire exposure. It brings together observations from real fires and laboratory tests, reviews the main physical theories (thermal stresses, pore pressure, and combined mechanisms), describes available experimental test methods, and summarizes how concrete mix design, material properties, geometry, and loading conditions affect spalling risk.

The novel contribution of this volume lies in the systematic consolidation of decades of previously fragmented research into a single coherent framework, complemented by practical recommendations for testing and design. These recommendations are supported by recent experimental campaigns and aligned with updated standards.

The book will be of interest to researchers developing new models and test methods; fire safety engineers designing structures to mitigate spalling; design offices and structural engineers addressing fire resistance in projects; manufacturers optimizing concrete formulations to reduce spalling risk; and technical control authorities and organizations involved in the assessment and approval of innovative construction products.
