Copper Veneer Frequently Asked Questions
Contact cement never fully hardens so there is a bit of liability there. If you have a means of clamping the copper in place, then I highly suggest using TC-20 because it dries rock-hard. TC-20 is so strong that it has been used for copper flooring around -scan equipment. Keep in mind that TC-20 takes 24 hours to cure.

Conditions Contributing to Underground Copper Corrosion
14 These are the carbon-copper cells associated with certain cinder fills, and the copper-in-soil-copper-in-concrete cell associated with on-slab construction. Copper is anodic to carbon, and corrosion can be expected to occur if the cinders used for backfill contain appreciable amounts of carbon. Moisture, however, must be present for this ...
Copper slag–hydrated lime–Portland cement stabilised marine-deposited
The aim of this research study was to assess the performance of marine clay treated with a binder incorporating Portland cement, hydrated lime and copper slag. Unconfined compression and split tensile tests were carried out to assess the distinct binder content effects and to correlate those responses with the porosity/binder index.
