Abstract:
ACI Committee 355, Anchorage to Concrete, introduced qualification requirements for post-installed mechanical anchors in cracked concrete as part of ACI 355.2-01. While ACI 355.2 contains the test requirements and acceptance criteria to qualify an anchor for cracked concrete, it does not describe in detail the methods for both forming and opening the cracks in concrete test members. This article provides guidance for initiating, opening, and controlling cracks during testing of an anchor for use in cracked concrete.
