ACI 355.4-11

This standard prescribes testing and evaluation requirementsfor post-installed adhesive anchor systems intended for usein concrete under the provisions of ACI 318. Criteria areseparately prescribed to determine the suitability of adhesiveanchors used in uncracked concrete only, or in both crackedand uncracked concrete. Criteria are prescribed to determinethe design parameters and performance category for adhesiveanchors. Included are assessments of the adhesive anchorsystem for bond strength, reliability, service conditions, andquality control. Special inspection (13.3) is required duringanchor installation as noted in 10.22. Table 1.1 provides anoverview of the scope.



Keywords: adhesive anchors; anchors; cracked concrete; fasteners; post-installed anchors; qualification procedures; uncracked concrete.
