Combined ultrasonic and rebound hammer determination (sonreb method): The C372M ultrasonic tester houses an integral data logger for data acquisition, processing and store of rebound hammer values. The acquisition of the rebound values is performed with manual or automatic mode.
As for the Automatic mode, the digital Matest test hammer mod C386M is directly connected to the ultrasonic tester through a cable. The measured rebound values are automatically transmitted to the C372M tester.
The combined test allow to rectify different inaccuracies that are typical of the simple rebound hammer test, and obtaining estimates on the compressive strength of the concrete, that cannot be obtained with the ultrasonic test, granting high accuracy and reliability of the results.
