    摘要: 高性能混凝土是20世纪80年代末90年代初,一些发达国家基于混凝土结构耐久性设计提出的一种全新概念的混凝土,它以耐久性为首要设计指标。区别于传统混凝土,高性能混凝土由于具有高耐久性、高工作性、高强度和高体积稳定性等许多优良特性,被认为是今后混凝土技术的发展方向。连续刚构采用悬臂浇注法施工,混凝土不仅要考虑以上性能,还要具有早强性、可泵性。文章结合吉林省图珲高速公路板石沟高架桥连续刚构高性能混凝土的施工实践,介绍了高性能混凝土配合比设计方法和设计过程,并对高性能混凝土配合比设计提出了一些建议和看法。 High performance concrete is a new concept of concrete. It is designed and proposed on the basis of durability of concrete structures by some developed countries in the late 1980’s and early 1990’s. The primary design index is the durability. Different from the traditional concrete, high performance concrete with high durability, high workability, high strength and high volume stability of many excellent properties, is considered to be the development direction of concrete technology in the future. By using the method of cantilever casting, continuous rigid frame concrete not only has the above performance, but also has the early strength and pumpability. Combining the construction practice of continuous rigid frame high-performance concrete of Banshigou viaduct in Tumen-hunchun Expressway of Jilin Province, this paper introduced high-performance concrete mix design methods and design process, and put forward a number of recommendations and views about high-performance concrete mix design.
