The air entraining concrete's shrinkage and creep were less than concrete which not content airentrained agent, and the durability performance was improved obviously.
混凝土的收缩和徐变较不引气混凝土相比较小；耐久性能明显改善。

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。

It was found originally that environment atmosphere could effect the entrainedair content of concrete.
