Introduction and scope

This standard prescribes testing and evaluation requirements for post-installed adhesive anchor systems intended for use in concrete under the provisions of ACI 318. Criteria are separately prescribed to determine the suitability of adhesive anchors used in uncracked concrete only, or in both cracked and uncracked concrete. Criteria are prescribed to determine the design parameters and performance category for adhesive anchors. Included are assessments of the adhesive anchor system for bond strength, reliability, service-conditions, and quality control.

This standard prescribes the testing programs required to qualify post-installed adhesive anchor systems for design in accordance with ACI 318 Appendix D. Appendix D requires that anchors be tested either for use exclusively in uncracked concrete or for use in cracked and uncracked concrete conditions, whereby it is understood that the presence of cracking may occur at any time over the service life of the anchors. Test and assessment criteria are provided for various conditions including loads - seismic and sustained, environmentally with regards to humidity and temperature, and determination if anchors are acceptable for use in cracked or uncracked concrete. Refer to Cook (2001) for a review of factors that influence adhesive anchor behavior. Refer to Fuchs (1995) for background on the concrete breakout design model and to Eligehausen (2006) and Zamora (2003) for a discussion of bond models for adhesive and grouted anchors. For a discussion of issues associated with the qualification and design of systems for post-installed reinforcing bars, refer to Spieth (2001).
