混凝土养护剂在地铁隧道管片中的应用研究

Research on Application of Concrete Curing Agent in Segments of Subway Tunnel

摘要:

混凝土管片的养护方式决定管片最终的力学性能和耐久性能。首先通过试验，对养护剂的基本性能进行研究。继而，进一步将养护剂养护与常规水溶液养护两种方式进行对比，探究养护剂养护方式对混凝土管片外观质量、强度、抗渗性能等的影响，验证了该种养护剂在地铁隧道管片中应用的可能性。

Abstract:

The curing method of concrete segments determines the final mechanical properties and durability of the segments. Firstly, the basic properties of the curing agent are studied by experiments. Then, two curing methods of the curing agent and the traditional aqueous solution are further compared to explore the effect of curing agent on the appearance quality, strength and impermeability of concrete segments. The possibility of this curing agent used in the segments of subway tunnel is verified.
