Preparing the substrate
- The substrate must be thoroughly inspected
- Any unsound material must be removed
- Prepare mechanically the substrate
- Surface defects must be repaired prior to placing Carbon Fibre Reinforced Polymer (FRP) Plates – use of epoxy material ) is preferred due to high strength development speed
- Adhesive strength of concrete shall be verified by pull of test (minimum tensile strength: 1.5 N/mm2)
- Provide clean dust free working surface
- Stick down the tape on the surface if no recess in concrete has been made
Unpacking Carbon Fibre Reinforced Polymer Plates
- Carbon Fibre Reinforced Polymer Plates will arrive on site packed as a coil in a box
- The boil of Carbon Fibre Reinforced Polymer Plate must bi handled carefully to avoid uncontrolled uncoiling and splitting the edge of the strip
- Gloves, mask and goggles are recommended when handling Carbon Fibre Reinforced Polymer Plates
Cutting Carbon Fibre Reinforced Polymer Plate
- Check the strip length on the structure
- Cut the plates with hacksaw
- Care should be taken to support both sides of the plate when cutting
- Avoid workers exposure to airbone carbon dust generated while cutting (i.e. use mask and gloves is recommended)
Preparation of Carbon Fibre Reinforced Polymer Plate
- Clean the plate bonding surface (the roughened, unlabeled surface) with colmar cleaner and a clean white cloth until all residual carbon dust is removed (i.e. the white cloth remains white after wiping the plate)
- In the case where design requires “staking” of the strips, the bottom surface of the strip (which is labelled) should be light sanded prior to the application of the second strip.
