Pull off adhesion test : choice and influence of the diameter of the dolly
Pull off adhesion test : choice and influence of the diameter of the dolly
(OP)
Hello,
I am a french material engineer.
I want to carry out pull out tests on coatings applied on steel surface and concrete surface.
So my questions are :
- Do you know why the diameter of the dolly is different between concrete surface (50 mm) and steel surface (20 mm or < 20 mm)?
- Is there an influence of the diameter of the dolly on pull out test results ?
Thanks for your answers

B.E.
You are judged not by what you know, but by what you can do.

The ultimate potential strength of a pulloff on concrete is much lower than on steel. I have seen steel pulloffs at 5000 PSI. Rarely would you see concrete pulloffs of 500 PSI.
