Are air entraining agents required in GFRC for freeze-thaw resistance?
Posted on 7/24/2014
No. GFRC has proven to have good freeze thaw resistance, without the use of air entraining agents, due to the glass fibers, high density and low water absorption. In fact, it is likely that the air entraining agent would be counter-acted by the defoamer in Forton® VF-774.
