Abstract— Concrete is the most widely used construction material worldwide. Strength of a concrete structure may have to be assessed without causing physical damage to it, due to various reasons like its monumental importance or the legal dispute on whether the strength of the concrete in the structure is satisfactory enough or not. In an attempt to meet the above demand, correlation and comparison between Destructive Test (DT) and Non Destructive Test (NDT) were carried out.
A total of 24 concrete cubes (150 mm x 150 mm x 150 mm) were cast with concrete mix ratio of 1:2:4. 12 cubes were tested destructively for compressive strength with compression machine and 12 cubes were also tested non-destructively with Schmidt Rebound Hammer. Compressive strength test results at curing ages (7, 14, 21 and 28days.) were collated and analysed.
The results obtained from the non-destructive testing method were correlated with the results obtained from destructive testing method. The coefficient of correlation between the two set of compressive strength was 0.988 which indicates a perfect relationship between compressive strength results from both methods.
Keywords— Compressive Strength, Non Destructive test, Destructive Compression test, Schmidt Rebound Hammer.
