Qualification of Post-Installed Adhesive Anchors (Part 1) (PDF)

Pdf Summary

The document is a report by the American Concrete Institute (ACI) Committee 355, detailing the standard ACI 355.4-11 for qualifying post-installed adhesive anchors in concrete. It was first published in August 2011, superseding the previous provisional version ACI 355.4-10. The document lays out comprehensive testing and evaluation requirements for these anchors, in adherence with design provisions of ACI 318. Testing and criteria address various use conditions, such as seismic and sustained loading, aggressive environments, temperature variations, and whether the anchors are suited for use in uncracked or cracked concrete.<br /><br />The document provides a detailed structure including chapters on general requirements, specific testing protocols, reliability and service-condition tests, and assessment methodologies. The first chapter introduces and scopes the application of the standard, specifying that it targets adhesive anchors of specific dimensions and in compliance with US standards, notably excluding certain aggressive environments and non-anchor applications like structural adhesiveness outside drilled holes.<br /><br />A detailed focus is placed on ensuring that adhesive anchors meet necessary criteria for bond strength and reliability under diverse environmental conditions. The standard mandates thorough testing for potential scenarios that may impact anchor performance. Additionally, it establishes comprehensive quality control measures and emphasizes the importance of proper installation and inspection practices to assure functionality and safety.<br /><br />The report also contains reference materials and contact information for the ACI, providing avenues for errata submissions and procurement of the full report through ACI University and ACI Store. It is detailed and technical, aimed at professionals competent to evaluate and apply the information in practical, construction-related projects, with a responsibility to align with safety and legal standards.
