Hello valued clients and contacts,

Concrete Structure Investigation’s response to the Covid-19 Level 3 alert, with the upgrade to Level 4 Wednesday midnight:

CSI can continue to work remotely on your queries for pricing and completing reports where data has already been collected., as our team can work remotely on these and share electronically for peer review.

Pull Off Strength Test

1. What is a Pull Off Strength Test?

Pull-Off Strength Testing applies pull load to Fibre Reinforced Polymer (FRP) laminate systems adhesively bonded to a flat concrete surface.

2. When would you use a Pull Off Strength Test?

When you want to conduct quality control and assessment of field repairs of structures using adhesive composite materials, such as FRP-wrapped concrete. The test determines the ultimate tensile strength an FRP system can sustain before detachment occurs.

3. What are the Benefits of a Pull Off Strength Test?

The quality of FRP-wrapped concrete is dependent to many factors, including bonding agent quality, workmanship, and the quality of the concrete substrate itself. With this test, the different failure modes will give insight to the weakest element that leads to detachment.

4. Limitations

The test is conducted following ASTM D7522.
