Is there one or two standard test methods used by the concrete industry to test concrete's adhesion to various materials (woods, cermaics, plastic, metals, etc.)? I am interested in what is the MOST common method(s) used by the industry.
TIA
 
Where new concrete is to bond to existing concrete, as in some construction joints, promote bond adhesion with something called a bonding agent. See literature from concrete accessory distrubutors.
 
Yes, there is a bond test or pull-off test for concrete coatings.; Check with ASTM - I can't remember the number, it was 25 years ago when I built my first CANDU reactor and we were testing epoxy liners. You coat the concrete sample, score the coating and concrete with a 2" diamond drill bit, glue on a 2" pipe cap, and record the tension required to pull the cap (hopefully with coating) off the concrete.
