ACI 355.4-19 (IN-LB) PDF Download

ACI 355.4-20 is a standard that outlines the qualification process for post-installed adhesive anchors in concrete. The standard specifies testing programs and evaluation requirements to ensure the anchors meet the design provisions of ACI 318. It covers a range of conditions, including seismic loading, sustained loading, aggressive environments, and reduced and elevated temperatures. The standard distinguishes between anchors that are acceptable for use in uncracked concrete and those that can be used in both cracked and uncracked concrete. It also provides criteria for determining the characteristic bond strength, accounting for reductions in strength due to adverse conditions, and establishing anchor categories and associated quality control requirements on the job site.
