大跨度桥梁预应力高强度早强混凝土质量控制

Prestressed high strength and early strength concrete quality control of the large span bridge

主要介绍大跨度桥梁预应力高强度早强混凝土在配制、浇筑、振捣、养护等环节的施工工艺及质量控制措施,指出该预应力高强度早强混凝土在工期控制、内外观质量、经济效益上都取得了较好效果,为同类工程积累了经验。

The author mainly introduces the construction technology and quality control measures of the large span bridge prestressed high strength and early strength concrete quality control on links of preparation,grouting,vibrating and maintenance,points out that the prestressed high strength and early strength concrete gets better effect on the project control,internal and external appearance quality and economical benefit,thus accumulating experiences for similar project.
