Abstract

Knowing the compressive strength of a reinforced concrete structure that has been casted can use non-destructive test that is Ultrasonic Pulse Velocity (UPV). Where the wave propagation velocity will be the main variable on the equation in estimating the value of compressive strength. UPV wave velocity is strongly influenced by the density of the object under test. Research to get compressive strength of a reinforced concrete structure with UPV measurement has been done. The study immediately found the value of concrete compressive strength without considering the effect of reinforcement. It is also based on the fact that concrete and reinforcing steel are different characteristics. Therefore, this research was conducted to determine the effect of concrete age and reinforcement on ultrasonic wave propagation velocity on UPV testing. The ultrasonic wave velocity in UPV test with concrete test object should be performed after the concrete is 28 days or in dry conditions. The reinforcement sequence within the reinforced concrete structure do not have a significant effect on the ultrasonic wave velocity.
