BOND-TEST
BOND-TEST
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).”
A disc is bonded to a prepared testing surface and a partial core is cut around the disc. The disc is then pull off with the handheld hydraulic pulling machine. The pull-off force register by the electronic gauge is divided by the cross-sectional area of the partial core to obtain the pull-off strength.
- To evaluate the in-place bond strength between a repair overlay or patch 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 evaluate the adhesion of diverse materials like metal plates, tiles, thick coatings, FRP’s, etc., on concrete or masonry surfaces
- Battery powered handheld hydraulic pulling machine with robust steel-aluminum body
- Digital display resolution = 0.1 kN
- Maximum force: 100 kN (about 22 MPa for 75 mm discs)
- Maximum stroke: 6 mm
- Accuracy of measurements: < 2%
- Operating conditions: -10 to 50°C, max. RH = 95%
- Memory capacity: 512 measurements (peak-value, time and date of testing)
- AMIGAS Software for PC communication and printout
- Coefficient of variation of replicate test results for the pull-off test method = 8 – 10% for 75 mm discs and 14 – 16% for 50 mm discs
