Pullout
Strength Test Procedure.
Perform pullout strength tests under dry and wet conditions as follows:
1.
Dry Condition (epoxy steel)
Cast three concrete
test blocks or cylinders, a minimum of 6 inches (150 mm) in width or diameter
by 12 inch (300 mm) in depth. Use concrete with a compressive
strength of 4000+/- 500 psi at 28-days Center a 6 3/4 inch (170 mm)
deep hole, drilled the diameter required by the manufacturer’s requirements for
installing a No. 6 (20M) rebar, in the block or cylinder by drilling or
forming. Dry the hole surfaces and clean the
holes following manufacturer instructions. Fill the hole with adhesive
materials according to manufacturer recommendations. Insert a No. 6 (20M)
deformed reinforcing bar 30 inches (760 mm) long, cleaned and degreased,
into the hole. Hold and center the bar perpendicular to the concrete
surface in the grout-filled hole during the curing period.
2.
Wet Condition (epoxy steel)
Cast three concrete
test blocks or cylinders, a minimum of 6 inches (150 mm) in width or diameter
by 12 inch (300 mm) in depth. Use
concrete with a compressive strength of 4000+/- 500 psi at 28-days.
Center a 6-3/4 inch (170 mm) deep hole, drilled the diameter required by the
manufacturer’s requirements for installing a No. 6 (20M) rebar, in the blocks
or cylinders by drilling or forming. Wet the hole’s
surfaces prior to applying the anchoring material by filling the hole with
water and letting stand for five minutes. Turn the samples over for two
minutes to allow the excess water to drain from the hole, Turn all samples over
to the upright positions and immediately fill hole with adhesive materials
according to manufacturer recommendations. Insert a No. 6 (20M) deformed
reinforcing bar 30 inches (760 mm) long, cleaned and degreased into the
hole. Hold and center the bar perpendicular to the concrete surface in
the adhesive-filled hole during the curing period.
Cure
Period. Cure the specimen at 77 ± 5 °F (25 ± 3 °C) for
24 hours.

Test Apply an axial load to the bar at a rate of 1/2 inch (13 mm)
per minute until the bar pulls out of the specimen, or the concrete block or
cylinder cracks or spalls. Record the failure mode and applied load.
