Pull off adhesion testing is widely used to assess the protective coating process It is also used to determine if a coating is fit for service in new construction and for repairs to existing structures The result is often critical to the acceptance or rejection of a coating process as the adhesion value quoted by the paint manufacturer can

While performing anchor pull tests we will look for various factors to determine the capability of your anchors Testing the failure load of an anchor and finding the resistance of supporting anchorage Finding the structural strength of the anchor system as well as the base material it is set within Testing base material to determine if it

Anchor bolt Pull Out Strength is the force required to pull a single bolt out of its foundation The separation can occur between the epoxy grout and the concrete foundation or it can occur between the anchor bolt and the epoxy grout itself This bulletin provides
test method serves as a means for uniformly preparing and testing coated surfaces and evaluating and reporting the results This test method is applicable to any portable apparatus meeting the basic requirements for determining the pull off strength of a coating 4 2
In order to test the pull off strength of a coating on concrete the technician would use one of the variety of pull off testers supplied by Humboldt such as Proceq s DY 2 Pull off Tester or our HC 2988A Bond Test Kit The bonding strengths of a wide and varied range of materials including concrete screeds repair mortars epoxy resin
NCHRP 639 – Adhesive Anchors in Concrete Under Sustained Loading Conditions 2009 – Determines creep resistance of adhesive anchors – Developed a standard test procedure for AASHTO NCHRP 757 Long Term Performance of Epoxy Adhesive Anchor
Recall the load used is the capacity of the anchor not the demand load on the anchor Also note that the calculated design value is inclusive of the strength reduction phi factor i e Design Strength phi Tn iii Multiply this value by 1 25 This is the test load which shall be used for proof loading 3
Anchor bolt tensile and shear test The Pull Out Test is one of the methods used to inspect an anchor s load carrying capacity This test determines the tensile strength capacity The tested load will be applied in the parallel direction to the anchor using a hydraulic pump with a load measuring system Displacement of the tested anchor is

These tests showed that the presence of water did not have an effect on the epoxy bond when anchor holes were cleaned dry and installed underwater but it
Anchor Site Testing may help to avoid the slow and error prone step of manually noting test results Hilti s latest generation of anchor testing equipment transfers readings including load versus displacement graphs directly to the analysis software – cutting out

The pull out test load and test requirement should be mentioned in the Approval letter In general it will be 1 5 x recommended load under a standard method for conducting tests in axial tensile forces based on the BS 5080 1 1993 the HST3 recommended load table is
Anchor Pull Testing At Applied Technical Services we frequently perform anchor pull tests to be used as a quality control measure When evaluating an anchoring system the rock bolt should be mounted in the same manner and method and in the same material it is envisioned or projected to be used in a construction
