Condition Assessment of Structure Through Non Destructive Testing—A Case Study on Two Identical Buildings of Different Age

Abstract

The experimental case study for the conditional assessment of a structure using the Non Destructive Testing methods; Rebound hammer test and Ultra sonic pulse wave velocity test, has been discussed in this project. Two identical structures in same environment but with different age were tested for their strength and quality of concrete by the non destructive testing methods to compare their existing condition. Tests were performed with same workmanship and accuracy thereby reducing the percentage of error for better comparison. The older structure between the two was found to have lesser strength and quality as compared to the younger one. This could be due to various causes and effects which have been discussed. The project was executed through literature survey in the relevant fields and then compared to conclude with some expected result, the instruments for testing at the site were resourced through consultancies which offer such services. Many structures were surveyed to find the most suitable one to perform the tests and draw results which prove significant for the structures’ quality comparison. Testing on structure was performed though Non Destructive Testing methods on the structure and finally results were analyzed to compare condition of the structures which were tested.
