Comparative Study of Concrete Structural Properties using various Non-Destructive Testing against Destructive Test

Abstract

Non-destructive testing is becoming a major tool for estimating the adequacy of concrete for existing structures. However, there is a need to establish reliability of the non-destructive testing equipment as compared to the conventional destructive test methods. The study focuses on comparisons conducted on a sample size of 24 concrete cubes prepared by two different batches of concrete ratios. i.e (1:2:4) and (1:1.5:3). This research study was designed to compare strengths and behavior of concrete using the two batches of concrete. Cubes that were tested at 03, 07, 14, and 28 days by using Rebound Hammer, Compression Testing Machine (CTM), Cut and Pull out (CAPO) test, Air permeability Coefficient and Ultra Sonic Pulse Velocity Tester available with the Council for Works and housing Research (CWHR). The results of all tests indicate that non-destructive test methods are by and large reliable and comparable to the destructive testing methods at CWHR.
