Testing the adhesion strength of building materialsMore info
To determine the bond strength/material strength of a wide range of construction materials
The force required to pull a specified diameter of coating away from its substrate provides an indication of the strength of adhesion between the coating and the substrate.
Using 50mm, 75mm or 100mm circular steel or aluminium discs for concrete, core a notch in the material under test to the depth of the bond surface. Attach the disc to the test area with epoxy adhesive. Centralise and fit the puller assembly and bridge to the secured disc and apply load until failure occurs. Relative to the force applied and the area under test a nominal tensile strength in Mpa for the material may be delivered.
