This book includes research papers on different disciplines related to composites. It contains research related to new topics such as nanotubes, fibres, admixtures added in cement and concrete. Additionally self-healing and self-sensing issues are presented. Environmental, and thermal-related topics are also discussed. Studies related to consolidation topics and alkali activation of clays are included. This blend of traditional and modern building materials, all having a common ground, the use of new technologies for improving fresh and harden state properties, make this volume interesting.
