Concrete Air Entrainment in Painted Walls

Concrete Air Entrainment in Painted Walls

(OP)
Do tilt-up concrete wall panels that will be painted require air entrainment?  I do not think they should but have not been able to find any information to back this up.

RE: Concrete Air Entrainment in Painted Walls

I have struggled a bit with this issue for several years.  I ended up settling on the following.  In southern and western climates with little or no freeze thaw I have not been requiring air entraining.  For northern climates, especially were there is a road, drive way, or parking lot adjacent to the building, I still use some level of entraining.  

The only real problem that I have encountered with air entraining is when the owner wanted the inside face of the panel to have a smooth trowled finish.  In these case, I have seen severe blistering.  If the inside face is to receive a broom or similiar finish, the air will not be detrimental.
