*Posted on behalf of a Hilti customer:
Which anchor should I use to fasten a structural steel beam to grout filled concrete block?
Hi Customer,
thank you for your question. Both chemical and mechanical anchors may be used in grouted CMU. If voids are present or suspected, Mechanicall anchors should not be used, and chemical anchors should only be installed in conjunction with a screen tube to prevent uncontrolled flow of the bonding material.
In hollow masonry, anchor strength is generally assumed to be based on the face shell thickness, which can be variable. Mechanicall options include the KWIK Bolt 3 Expansion Anchor, KWIK HUS or KWIK HUS-EZ Carbon Steel Screw Anchors. Adhesive option is HIT-HY 70 Adhesive Anchor System. Please feel free to reach out any time, if you need additional information.
Best Regards
Jorge
