| A pullout test measures the force required to pull a specially shaped steel rod or disc out of the hardened concrete into which it has been cast. The procedure requires the steel rod to be tested to be gripped using an attachment that is connected to a hydraulic jack. Once connected force is applied to the hydraulic jack until failure of the bond strength between the embedded steel and the cast element or until the load exceeds the design requirements without showing any signs of failure.
