- Abstract:
Despite the high technological improvements in construction science and technology, the life expectancy of civil structures still raise some questions because many of them become structurally deficient years before the end of their projected service life expectation. Some of the most significant reasons are improper material selections which have low resistance environmental conditions, inadequate and/or late inspection and insignificant maintenance. Consequently, the dissertation presented herein will develop a comprehensive understanding with regard to selection of proper materials with high durability and provide quantitative and objective information in damage detection. The projects will consists of (1) selection of advanced construction materials such as high-strength and high-performance concrete in order to improve long-term durability and therefore service life; (2) new innovations in inspection technologies including Microwave and Acousto-Ultrasonic for early inspection of durability related problems; (3) durability performance of recent rehabilitation techniques such as carbon fiber reinforced polymer (CFRP) strengthening and crack injection using epoxy based materials. The research results revealed that a proper optimization of local materials to produce high-performance and high-strength concrete improves the long-term durability. CFRP strengthening and crack injection using epoxy based materials are excellent sources of rehabilitation techniques; however, harsh environmental conditions may cause stiffness loss. New advances in Microwave Technology and Acousto-Ultrasonic Technique were proven to be an effective means for the investigation of detection of surface defects between CFRP and concrete substrate.
