Effects of Epoxy Coating on Anchorage and Splices of Welded Wire Fabric

Stacy J. Bartoletti and James O. Jirsa


The effects of epoxy-coating on anchorage and splices of WWF were investigated. The program included weld shear tests, pull-out tests of bars with and without cross wires, and slab tests with splices in the welded wire fabric. Comparison slabs containing spliced fabric were cast with no coating on the welded wire fabric for comparison with coated fabric.

The performance of comparison specimens indentical in all respects, except for the epoxy coating on one and uncoated wire fabric in the other, indicated that the coating had very little or no influence on strength, stiffness and cracking patterns.
