Can't think it would be very good. We use PVC pipe around tubing to protect the tubing from the concrete. After we are done - we use a jack hammer or manual sledge to remove the concrete. Comes off fairly easily esp if there is any residual "junk" on the PVC.
I wouldn't normally look to develop strength there, however, I am in a situation where we need to attach to the PVC for a minimal amount of load and I want to verify that I will not pull the PVC away from the concrete. We could possibly perform an in place test on the condition, but, I was hoping for a bond value to start with.
