摘要
混凝土裂缝是混凝土工程常见通病。从设计、混凝土原材料、混凝土配合比设计及施工、张拉工艺等方面采取了一些技术措施,有效地控制了900 t铁路预制箱梁混凝土表面裂缝产生。
Concrete cracking is a common problem in concrete construction. Some technical measures were taken from the viewpoints of designs, raw material and mix designs of concrete and concrete construction and tensioning techniques to effec- tively control the surface cracks in concrete for the 900 t precast box girders for railway construction.
