The abrasion resistance of airentraining concrete has little changes when salts added into concrete.
引气混凝土中掺盐后耐磨性基本不变。

It was shown in study that by moderately added airentraining agent in concrete would obviously enhance the concrete durability.
通过研究发现，在混凝土中适当引气可以大幅度提高混凝土的耐久性能。

The airentraining concrete's shrinkage and creep were less than concrete which not content air entrained agent, and the durability performance was improved obviously.
