This is a comprehensive guide to autoclaved aerated concrete (AAC) for designers, specifiers, users and manufacturers. It provides a model code of practice for the structural use of AAC and provides designers with a complete guide to the structural use of AAC in structural applications in building. The second part contains the complete suite of RILEM Recommendations for specification and testing of AAC. Recommendations for further research, structural design examples and a glossary of terms are also included. The book has been prepared by two international groups of specialists under the auspices of RILEM (The International Union for Testing and Research Laboratories for Materials and Structures). This book should be of interest to architects and structural engineers working in professional practices, as well as building contractors, researchers, manufacturers and testing authorities.
