Air content in concrete
Air content in concrete
(OP)
I have a project in which I've just received the concrete mix design. The air content is 10% (by volume). I know the normal range should be around 6% to 7% (if subject to freeze/thaw) so I'm trying to figure out what would be the adverse effects of high air content in concrete. I know it may affect the compressive strength. Does anyone else know what may be other effects?

When it comes to design, you design for range that is specified and use the history provided. I base this on a "hands-on" 3 concrete credit course in college when we quickly tested a truckload. - A lot of sweat and mess, but it paid off!!
