Category: Repair Quality

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
