Acoustic Concrete Tester (ACT)
The Acoustic Concrete Tester (ACT) determines the thickness of structural elements such as concrete pavements, slabs, retaining walls, tunnel liners, foundation footings, and more. In addition, the ACT may identify defects such as delaminations, spalls and horizontal flaws. The ACT tests structures as thin as 75 mm and as thick as 600 mm.
The ACT is precise, light, battery operated and rugged for field use in all weather conditions. It uses Ultrasonic Echo Technology. It electronically generates a broadband pulse that includes all frequencies required to accurately determine the thickness of the structure.
The ACT eliminates the need to manually impact the structure, the need for coring, and the need to assume a concrete wave speed prior to the test.
Measuring thickness with the ACT consists of placing two small probes on the structure to be tested and touching the ACT screen. A telescoping pole helps test hard to reach structures. As the structure responds to its natural frequency, its thickness is displayed on the high visibility ACT screen. The ACT also calculates the wave speed of structures of unknown thickness.
