Entrained Air in Concrete for Drilled Piers
Entrained Air in Concrete for Drilled Piers
(OP)
I am working on a project in Austin, Texas that has drilled piers as part of the foundation. This is a city building, so they like us to use their pre-approved concrete mixes. The mix that they have pre-approved for piers has air entrainment. We used Masterspec to put together our specs, and there is a line that says air entrained concrete should not be used for drilled piers. The contractor just pointed out this discrepancy to me. I would like to allow him to use the mix with entrained air. I was wondering if any of you know why it would be an issue to use air entrained concrete for piers.
Thanks
Thanks

Of the 1000's of piers I designed and had built in Texas through the 1980's I never used air in them - nor had contractors request that it have air.
The only reason I could imagine needing the air is if the pumping of the concrete would be facilitated by the air.
