摘要：
The frost-salt resistances of concrete were investigated according to the CDF methodeffects of air void systems introduced by different air entraining agent. The results showed that the frost-salt resistance of concrete increased with the decreasing of spacing factor and increasing of air content. The speed of frost-salt scaling of concrete was reduced when the spacing factor less than 0.200mm. The results also showed that the frost-salt resistance of concrete of different surface exist difference. The frost-salt resistance of concrete can improve by controlling of the spacing factor not the air content.
