高性能混凝土在贵广高铁怀集制梁场的研究与应用

The Study and Application of the High Performance Concrete to Huaiji Beam Casting Yard for Guiyang–Guangzhou High Speed Railway

高性能混凝土是一种新型高技术混凝土,是在大幅度提高普通混凝土性能的基础上采用现代混凝土技术制作的混凝土。随着我国建筑行业和高速铁路的快速发展,高性能混凝土的应用越来越广泛,充分显示出其高性能的优越性。贵广怀集制梁场对C50高性能混凝土的研究和应用,获得了成功,文中对高性能混凝土性能、特点及在工程中的研究、应用和实际施工情况作了介绍。

The high performance concrete is of high--technology, which is a new type of concrete fabricated by using the modern concrete technology based on substantially improved ordinary concrete performance. With rapid development of both civil construction industry and high speed railway, the high performance concrete is being used more and more extensively, thus fully displaying its advantage. Guiyang -- Guang- zhou Railway Huaiji Beam Casting Yard has achieved success in both study and application of C50 high performance concrete. This paper briefs the performance and characteristics of the high performance concrete, its study and application in the project and practical construction.
