This proceedings volume consists of papers focusing on repairing, maintaining, rehabilitating, and retrofitting of existing infrastructures to extend their life and maximize economic return. Moreover, structural performance and material durability are discussed. Contributions fall under the following headings: (i) Concrete durability aspects, (ii) Condition assessment of concrete structures, (iii) Modern materials technology, (iv) Concrete repair, rehabilitation and retrofitting, (v) Performance and health monitoring, and (vi) Education, research and specifications. Major attention is paid to innovative materials for durable concrete construction, integrated service life modelling of reinforced concrete structures, NDE/NDT and measurement techniques, repair methods and materials, and structural strengthening and retrofitting techniques. For researchers and practitioners in structure and infrastructure engineering. Set of book of abstracts (546 pp) and a searchable full paper CD-ROM (1564 pp).
