高速铁路抗冻混凝土含气量与强度的对立与统一技术研究

Technique Research on the Opposition and Unification of Air Content and Strength of High-speed Railway Anti-freeze Concrete

从抗冻混凝土的抗冻机理和引气剂的作用入手,论述了抗冻混凝土含气量与强度对应关系研究方法和试验情况,以及将该技术研究成果应用到京沪高速铁路一标段天津特大桥的施工情况,实践证明该研究方法是正确的,可以指导施工。

tarting with the antifreeze mechanism of antifreeze concrete and the function of air-entraining agent,this article explores the approach and experiment of the study on the correspondence between air content and strength of antifreeze concrete as well as the application of the methods in the construction of Tianjin Bridge in Beijing-Shanghai High Speed Railway.Result shows such approach is correct and can be used to guide construction.
