efficient ultrasonic pulse velocity for concrete testing

Ultrasonic pulse velocity - Concrete

The velocity of a pulse of ultrasonic energy in concrete is influenced by the elastic stiffness and mechanical strength of the concrete. The equipment consists of two transducers, usually in the form of metal cylindrical heads, one of which is used to transmit an ultrasonic pulse and the other is a receiver.

APPLICATION OF ADVANCED NON-DESTRUCTIVE TESTING

transmitted through sound concrete than through poor concrete. Using equipment Cs-97, this test measures the apparent time between probes, not true velocity. The apparent wave speed through concrete can be calculated knowing the distance and the time taken by an ultrasonic pulse to go through the material between a transmitter and a receiver.

Reinforcement effect on the ultrasonic pulse velocity in

Keywords: Concrete, nondestructive testing, ultrasonic pulse velocity, effect of reinforcement Abstract In practice it is often required to determine the technical condition and the load carrying ca-pacity of reinforced concrete. The quality of the constructions is also characterized by the struc-tural properties of the concrete.

Comparison of Five Standards on Ultrasonic Pulse Velocity

The essence of the pulse velocity method is that the transition time of an ultrasonic longitudinal pulse (wave) is measured in concrete. From this, the pulse velocity can be calculated, and inferences are drawn concerning the strength or overall quality, or both, of the concrete.

Ultra Sonic Test Concreate in Dubai - Ultrasonic pulse

The pulse velocity in a material depends on its density and its elastic properties which in turn are related to the quality and the compressive strength of the concrete. In ultrasonic testing, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect

Investigation of the Potential for Evaluation of Concrete

Although most applications of this test focus on the inspection of metals, ultrasonic pulse transmission technique has been shown to be useful also for testing concrete elements. UPV have already been applied to new and old structures, slabs, columns, walls, fire damaged areas, hydroelectric structures, pipes, prefab, and prestressed beams [ 8 ].
