　　In order to evaluate the quality of air entraining agent (AEA) quickly and effectively.Air void parameters of fresh concrete with different air entraining agents were studied by Air Void Analyzer (AVA).The spacing factor and durability index of hardened concrete were tested and the relationship between the surface tension of air entraining agent and frost resistance of concrete was compared.
