1·The air entraining concrete's shrinkage and creep were less than concrete which not content air entrained 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。
2·It was shown in study that by moderately added air entraining 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。
3·The measuring methods of air contents and the appropriate adding quantities of air entraining agent in its concrete were put forward.
提出路面碾压混凝土含气量测定方法及引气剂适宜掺量；
4·When GCL1 combined with water retaining admixture HEC and air entraining agent, it will further improve the water retaining performance and increase the early stage and long term compressive strength.
GCL1与保水剂hec、引气剂复配时，改善了水泥净浆的保水性能，提高了硬化水泥的早期及后期抗压强度。
