This book presents the work done by the RILEM Technical Committee 227-HPB (Physical properties and behaviour of High-Performance Concrete at high temperature). It contains the latest research results on the modelling of concrete behaviour at high temperature. Some monographs on the subject have been published already but generally they do not cover the whole range of possibilities which are encountered in the literature as well as in practice. Moreover, there has been a rapidly increasing development of computational models during the last twenty years, which deserves attention. Therefore, it is the aim of this report to compile and present most of the tools that are proposed in the literature and are nowadays available for practice in some commercial computational packages. The book is divided in 3 main chapters dealing with:-              engineering modelling-              advanced modelling-              constitutive parameters including hydral, thermal and mechanical parameters. The results presented especially target a group of users composed by universities and research laboratories, building material companies and industries, material scientists and experts, building and infrastructure authorities, designers and civil engineers.

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.

This book presents the work done by the RILEM Technical Committee 227-HPB (Physical properties and behaviour of High-Performance Concrete at high temperature). It contains the latest research results on the behaviour of high-performance concretes at high temperature.The book presents the state of the art of experimental data on High-Performance concretes and it collects and synthesizes useful data about concrete behaviour at high temperatures. The book is divided into independent chapters dealing with degradation reactions in concrete exposed to high temperatures; mass transport properties; thermal properties; and mechanical properties.The results presented especially target a group of users composed by universities and testing laboratories, building material companies and industries, material scientists and experts, building and infrastructure authorities, designers and civil engineers.
