How does improper conc. consolidation affect strength?
How does improper conc. consolidation affect strength?
(OP)
I have cast in place formed walls that were not properly vibrated to consolidate the concrete.
How does this affect the strength? Are there any references or articles that address this?
Is there anything that can be done to repair this structurally or would any repair be just cosmetic?
Thanks!!

if the result is some minor honeycombing, then do as civilperson mentions with chipping and repair. if the problem is something more than surficial, i would not want my stamp on it.
you can evaluate the area (at the expense of the contractor) using ndt methods to more fully check the entire area. then, perform coring to have a better look inside the "suspect" areas and perform compressive strength breaks.
i've even seen times where the contractor was forced to hire their own structural to evaluate the scenario and take responsibility for the wall.

Cover to reinforcement would be reduced locally.
also a look at where the concrete is going to be in compression - if the voids are only on the side walls then this may not effct strength much, but this may effect shear capacity in a high shear zone.
These dont account for invisible voids that may be inside the concrete.
