Abstract

The aim of this research is to establish the characterization of concrete by using the Non Destructive Test (NOT) of Ultrasonic Pulse Velocity (UPV). NDT is the process of examining or evaluating materials or components without destroying the function, serviceability and product structure test. NOT is used in industrial, manufacturing, and fabrication and inspection services widely to ensure product quality. A general series of tests which are compression test, and UPV was carried out at laboratory to obtain a correlation of the NDT results with compressive strength. 27 concrete cubes of sizes 100 x 100 x 100 mm and 9 concrete prism of size 100 x 100 x 500 mm has been made and subjected to water curing for 28 days for concrete grade of G30, G35 and G40 with three different water cement ration which is 0.4, 0.6 and 0.8 for each concrete grade. To get the exact result of the strength, compression test applied to the concrete cube. Before the compression testing applied, the cube strength checked by using UPV. The data obtained from each test has been evaluated and analysed. From this research, the data that only consider are grade concrete of G30; w/c 0.6 and G40; w/c 0.4. The result shown that the concrete strength of concrete grade G30 with w/c 0.6 are too high for experimental data (36. 71 MPa) compare to the laboratory data that achieve the target strength (28.80 MPa) and concrete grade G40 with w/c 0.4 too lower than the laboratory work, 35.80 MPa which is 25.04 MPa. However, for UPV test result, data shown that the cumulative results of the testing of ultrasonic pulse velocity (UPV) is greater than 4.5 km/s except for concrete prism of grade G40 with w/c: 0.4 but for all the result for concrete grade G30; w/c: 0.6, are in the range of excellent quality.
