Condition Assessment and Structural Repair of RCC Structures - Case Studies
Journal Title: JOURNAL OF ADVANCED RESEARCH IN CIVIL AND ENVIRONMENTAL ENGINEERING - Year 2018, Vol 5, Issue 3
Abstract
In the present paper, we have discussed the case studies of condition assessment & repair done on two RCC structures of 40 years old 150 mtrs. high, RCC Chimney and 25 year old Turbo Generator (TG) foundation in Thermal Power Stations located in semi-arid region in India. Condition Assessment study using Non Destructive Evaluation techniques was carried out on both structures for finding out the cause & extend of distress. Repair methodology i.e Surface preparation & Sand blasting reinforcement treatment, epoxy grouting, bond coat polymer modified mortar etc. was proposed based on the test results obtained. Non Destructive Evaluation Techniques like Rebound Hammer, Ultrasonic Pulse Velocity, Core extraction and Pull off Test etc. were also done to verify the effectiveness of repair work.
