This book captures the state of the art of the durability of fibre-reinforced strain-hardening cement-based composites (SHCC) and the durability of structures or structural elements manufactured in full or in part with this class of modern construction materials. Highlights include:-       Reflection on durability performance of existing applications in patch repair, a water reservoir and highway bridges.-       Guidelines for tensile testing towards durability assessment of cracked SHCC.-       New crack pattern related ingress rate indices for water and chloride into cracked SHCC.-       The influence of low and high temperatures on SHCC durability performance.-       The mechanism of crack control reducing ASR and corrosion rate, and results on chloride-induced corrosion of embedded steel reinforcement.-       Self-healing of cracks in SHCC. -       A conceptual durability design framework for SHCC and R/SHCC structures and members.
