Evaluation of Compressive Strength by Non- Destructive Test Using Ultrasonic Pulse Velocity With Maximum Size Aggregate (10 And 20)mm

الملخص

The concrete is tested non destructively to determine its mechanical properties (compressive strength) which is considered as the main property and the parameter used in its evaluation. This research aims to establish a fairly accurate relation between the ultrasonic pulse velocity and the concrete strength. The concrete was poured in the moulds [(30) cubes of size (150X 150X150)mm] are used to test ultrasonic pulse velocity for each size 10mm and 20mm coarse aggregate. The samples tested by ultrasonic test with direct ultrasonic pulse velocity (DUP) for each sample. The results obtained from the experimental work are analysed and studied by using statistica software. An empirical mathematical equation is derived by using statistic software program. In this paper the effect of maximum size of aggregate (20mm and 10mm) size on the result of ultrasonic pulse velocity.
