The results show that carbonation resistance of air-entrainedconcrete are evidently better than that of ordinary concrete at equal strength.
结果表明：在同强度条件下，引气型混凝土的抗碳化性能显著高于普通混凝土。

As a main measure to improve the frost resistance of concrete, air-entrainedconcrete has been applied to many kinds of engineering and has got very clear financial and social effects.
The air entraining concrete's shrinkage and creep were less than concrete which not content airentrained agent, and the durability performance was improved obviously.
