ICC-ES AC Interim Criteria for Inspection and Verification of Concrete and Reinforced and Unreinforced Masonry Strengthening Using Fiber-reinforced. Accordance with. ICC-ES AC ADVANTAGES. DESCRIPTION/SUGGESTED SPECIFICATIONS*. The % epoxy resin and hardener are completely mixed. As such, Hilti maintains ICC-ES evaluation reports for adhesive anchors in concrete according to AC and in masonry according to AC I hope I have.

For post-installed mechanical anchors, anchors must be qualified to the criterion in the ACI Appendix D will now formally be placed in the body of the Code as Chapter Underwriters’ Laboratories of Ca308.
Society for Protective Coatings. National Institute of Standards and Technology.
National Concrete Masonry Association. The creation of the threads in the concrete gives the screw anchor some advantage in cracked concrete where a small-narrow crack intersecting the threads has only a minor reduction on tension capacity. Deep embedments are often difficult to achieve because the friction of cutting a thread can exceed the torsional capacity of the screw shank and fail the steel in torsion. United Kingdom Highways Agency.
Standards of accredited organizations or ic-ces agencies. Although the design procedure for screw anchors has not been codified, they are gaining acceptance in building practice as a reliable fastening element Olsen, et.

STRUCTURE magazine | Post-Installed Anchors
In 12 years, we have codified anchorage design procedures and developed anchor qualification standards that have greatly raised the reliability bar for anchors used in practical design conditions. Neal may be reached at nsanderson sgh.

Geosynthetic Institute Test Methods and Standards. As of 15 Januarythe following will be required: Jcc-es Organization for Standardization. Pullout failures look very much like bond failures for adhesively bonded anchors. Reference should be made to a paper by Hoermann-Gast for additional information.

This was a conscientious decision by the Code Committee at the beginning of the reorganization work, because: Qualification For post-installed mechanical anchors, anchors must be qualified to the criterion in the ACI Organisation for Economic Co-operation and Development.
To provide the mechanical interlock to the concrete, the screw anchor cuts a thread into the concrete during the installation process. But unlike other chapters in the re-organized Code, Chapter 17 essentially remained an untouched clone of Appendix D.
