摘要
在贵州修建高速公路,多处于山区地带,使用细集料主要以机制砂为主。机制砂高性能混凝土在耐久性、工作性和体积稳定性等方面的良好性能,已在不少重要工程中被采用。本文以贵州省思南至剑河高速公路桥梁工程为依托,重点阐述C55机制砂高性能混凝土配合比设计及在实际施工中的相关经验,为西部山区类似工程提供技术参考。
The highways built in Guizhou Province are mostly located in mountainoud areas,and the fine aggregate used in them is mainly manufactured sand.Due to the excellent properties of high durability,high workability and volume stability,high-grade concrete with manufactured sand has been applied to many projects.Based on the bridges located at Sinan-Jianhe highway,the paper introduces some experiences acquired from the process of C55 high-grade concrete proportioning design and the construction procedure,for reference of similar project in the western mountainous areas.
