Abstract:The objective of this project was to evaluate the performance of currently specified epoxy adhesive
anchor systems on various epoxy-coated rebar under seismic, creep and tensile loading. Previous testing of
dowel bonding materials for use in hardened concrete was performed on plain rebar, raising the question of their
performance on epoxy coated rebar.
The epoxy-coated rebar was found to meet the requirements of ICBO-AC58, Section 5.3.7.2.4,
“Conditions of Acceptance” for tension and seismic loading when bonded into hardened concrete using an epoxy
adhesive. However, the epoxy-coated rebar did not meet the requirements of the Caltrans
Augmentation/Revisions to ICBO-AC58, Section 5.3.3.2, “Conditions of Acceptance” for creep loading when
bonded into hardened concrete. The rebar bonded with Covert Operations CIA-Gel 7000 was found to meet the
creep requirements, whereas the rebar bonded with Simpson SET22 and Red Head Epcon C6 did not meet the
conditions of acceptance for creep loading.
It was also noticed that, when compared to the manufacturer test data, the epoxy-coated rebar
outperformed uncoated rebar in allowable tensile loads for two of the three epoxies tested. Simpson SET22
adhesive under performed the manufacturer test data.
