The BOND-TEST is used to conduct a pull-off test in accordance with ASTM C1583, "Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension (Pull-off Method)."
The obtained pull-off strength can be used for the following purposes:
• To evaluate the in-place bond strength between a repair overlay and the substrate
• To evaluate the in-place tensile strength of concrete or other materials
• To evaluate the effect of surface preparation procedures on the tensile strength of the substrate before applying a repair material or overlay
• To estimate the in-place compressive strength of surface concrete using the following approximate relationship between tensile strength ft (MPa) and compressive strength fc (MPa)
