Qualification of Post-Installed Adhesive Anchors (Chapters 4 & 5) (PDF)

Pdf Summary

The document, "ACI 355.4-11," is a standard authored by the ACI Committee 355, detailing the qualifications for post-installed adhesive anchors in concrete. This standard, updated from the provisional ACI 355.4-10, specifies the testing programs and evaluation requirements for adhesive systems used in concrete under the design provisions of ACI 318. It involves various conditions of use such as seismic loading, sustained loading, aggressive environments, and varying temperatures. The criteria also determine the acceptability of anchors for use in cracked and uncracked concrete, establishing necessary bond strengths, anchor categories, and site quality control requirements.<br /><br />The publication includes detailed contents extending from basic introductions, scope, and definitions (Chapters 1 and 2) to general and specific test requirements (Chapters 3 to 14). The main focus is on the reliability and performance of adhesive anchor systems through rigorous testing methodologies tailored to different conditions. Each chapter outlines specific requirements for test specimens, anchor installation, and testing procedures, emphasizing aspects like tension capacity, shear capacity, member thickness, and installation conditions.<br /><br />Test samples for evaluation must be randomly selected and verified against the production specifications, while concrete for testing needs to adhere to strict standards regarding strength, composition, and age. Additionally, the document mandates that changes in adhesive products or installation procedures undergo review to verify consistency with the original qualification.<br /><br />This ACI standard serves as a reference for professionals competent in assessing these materials and takes no responsibility for interpretation errors. Detailed amendments or embedding this standard into contract documents requires restating its principles in mandatory language.<br /><br />For full document access, including complete testing protocols and appendices, visit the ACI Store or ACI University, as this excerpt provides a summarized preview intended for educational use within ACI University.
