What are epoxy anchors used for?
Resin epoxy anchors are very useful when installing rebar or threaded rod into deep holes or embedments. With a longer working time, resin epoxy anchors provide the installer great flexibility and more time to fill the hole and insert the anchor element.
How strong is anchoring epoxy?
A 5/8” diameter threaded rod in a 3/4″ diameter hole embedded to a 5-5/8” depth and cured at 75 °F for 24 hours in 3,500 psi concrete will yield an ultimate pullout strength of 28,000 lbf (124 kN). At the minimum load time of 4 hours in the same conditions the ultimate pullout strength is 7,000 lbf (31 kN).
How do you install epoxy anchor bolts in concrete?
Project Instructions
- Drill a hole 1/16 to 1/4 inch larger than the diameter of the threaded rod or railing you are setting.
- Blow out the dust from the bottom of the hole using cans of compressed air.
- Remove any remaining debris from the hole using a nylon brush.
- Insert the anchoring epoxy cartridge into the caulk gun.
How strong is concrete epoxy?
One of the primary things is the strength. When the epoxy is cured and hardened, it cures around 10,000 psi. Standard concrete usually runs between 4,000 and 5,000 psi.
How strong is epoxy in concrete?
How do you use epoxy anchors in concrete?
Insert the treaded rod or rebar to the bottom of the hole while turning clockwise. Remove any excess epoxy from around the hole with a putty knife or piece of cardboard. Leave the anchor un-disturbed until the cure time has passed. Remove and discard the static mixer nozzle and replace the cartridge cap.
Will epoxy bond to concrete?
When equal volumes of the resin and hardener are mixed, they react to produce a tough, rigid, high-strength bond. You can use epoxy resin for concrete to repair, fill, bond, and rebuild concrete surfaces.
