摘要：

Now the highspeed railway development is rapid in China. In view of the quality and the features of production technology of railway pre-concrete prefabricated box girder, the experiment researches five kinds of Pumping Concrete, which are composed of different significant slurry. Through researching the Mechanical, conductive, shrinkage and creep properties of specimen, it comes to a conclusion that the main compounding principle of low shrinkage, creep and high-performance concrete of railway box girder is adopting low water and right amount of mineral admixture.
