A study on repair of concrete structure using non destructive tests

Abstract

Although reinforced concrete is designed according to codes / standards, the construction process does not always take sufficient care. As a result, the buildings tend to exhibit symptoms of deterioration, often less than 10 years of service life, prompting early restoration and repair work. The corrosion of Reinforced Concrete systems, however, is regarded as a prime concern. It requires regular maintenance on one side, and many structures on the other side call for widespread repair, rehabilitation. Over a period of time, as these structures get older, we see some weakening or decay of them with subsequent distress in the form of cracking, fracturing, delaminating, corrosion etc. These deteriorated structures can be rehabilitated using various forms of admixtures & new materials for repair. This paper aims to suggest strategies for repairing, rehabilitating RC structure with the help of a case study. In the case study of the structure involved the main focus was on determining and correlating the results of two non-destructive tests with the purpose of suggesting appropriate sustainable measures for structural rehabilitation.
