机制砂高强高性能混凝土在特大桥中的应用技术探讨

Application of High-Strength High-Performance Concrete with Machine-Made Sand in Super Large Bridge

鉴于国内桥梁混凝土制备与施工技术相对落后,尤其高强度等级机制砂混凝土在贵州地区重大工程中应用较少的现状,结合实例,针对桥梁结构采用机制砂高强高性能混凝土的情况,总结出C60机制砂高强高性能混凝土拌合、运输、浇筑和养护技术。

In view of that the preparation and construction technology of concrete for bridge is relatively backward in China, especially the high strength concrete with machine-made sand is seldom used in important projects in Guizhou Province, aiming at the application of high strength and high performance concrete with machine-made sand in bridge structure, the paper sums up the mixing, transportation, pouring and curing technologies of high strength and high performance concrete with machine-made sand C60 combining with the practical case.
