Re: Rusted rebars

[Subject Prev][Subject Next][Thread Prev][Thread Next]
As long as the rusting has not causes significant reduction in
cross-section by pitting, it should not cause a problem.

Is there any reference/standard regarding rusted rebars to be poured
with new slab? We have an existing structure with some exposed rebars
left unprotected for several years. Those bars were designed to be
lapped for later phase of construction. Can someone use wire brush to
brush off the rust and reuse them for the lapping?    

Any suggestion or help will be appreciated.
