Epoxy Coated Rebar
Epoxy Coated Rebar
(OP)
I am doing rehabilitation of a concrete structure. The plan is to chip of the existing concrete; and to expose the existing epoxy coated rebars and leave them in place; and then to pour the new concrete. Before pouring the concrete, how do I clean the epoxy coated rebars? I understand that for black we can abrasive blast clean. I do not want to replace the existing rebar coz it is hard in construction point of view.






RE: Epoxy Coated Rebar
Why is the rehab required? If the bars are corroded, you will need evaluate the remaining strength of the bars, and supplement or replace if required.

Can you please help me silence them by giving us some more background information.
RE: Epoxy Coated Rebar
Are you able to develop adequate bond in the existing bars within the new concrete? Perhaps a rough sketch would be useful.

There is map cracking at the surface of the sidewalk of a bridge. The rebar is fine according to the condition report. Therefore we are planning to replace the top portion of concrete only.
