About

Rebound Test

Features
Read full description

Rebound Assistant is an auxiliary calculation tool APP for testing the compressive strength of concrete using the rebound method. Rebound Assistant incorporates multiple national standards of the People's Republic of China, including the Technical Specification for Inspecting Concrete Compressive Strength by Rebound Method (JGJ/T23-2011), the Technical Specification for Strength Testing of High-Strength Concrete (JGJ/T294-2013), and the Technical Standard for Site Testing of Masonry Engineering (GB/T 50315-2011), as well as local testing technical specifications from various provinces, municipalities, and districts. It contains over 60 calibration curves. When inspectors arrive at the testing site, they simply select the corresponding testing specification and manually input the rebound values from the rebound hammer into the Assistant. The Assistant then automatically and instantly calculates the strength results for the test area, making it as convenient and fast as using a calculator.
