Ultrasonic Pulse Velocity Testing
Ultrasonic Pulse Velocity Testing is non destructive technique which is used to check the quality of Concrete, In this method of testing we identify internal cracks, voids, strength and compaction quality of the concrete structure. In this method we find out the velocity of pulse inside the concrete. The higher velocity shows the good quality and lower velocity shows the bad quality of Concrete. Velocity can be calculated by formula:- (V) = Distance b/w trns. & rcvr. (L) / Reading of machine or time take by pulse (t) There are three methods of Ultrasonic pulse velocity technique. 1:- Direct Method 2:- Semi Direct Method 3:- Indirect Method 1:- Direct Method:- This method is m...
