Abstract:
A review of ACI published data on air-entraining concrete, this paper summarizes methods of control and the effect of air entrainment on durablity, plasticity and workablity, strength, resistance to abrasion and other properties of concrete. The effects of variations in cement and water content, sand-coarse aggregate ratio, mixing time and the use of calcium chloride as an admixture are described. Changes in technique necessary to sucessfully place, vibrate and finish air-entraining concrete are pointed out. A detailed bibliography follows.
