The Design of Mix Proportion of High-Performance Concrete for Passenger Dedicated Railway Based on Overall Calculation Method

Abstract

The main structure of passenger dedicated railway serves in complex physical environment, so its high durability is expected. In contrast to normal HPC applications, higher requirements are addressed for the application in passenger dedicated railway, which include control of raw material quality, selection of HPC design strength, and mix proportion design procedures. In this paper, the choice of HPC constituents, the principles of mix proportion design, and the design of HPC mix proportion for passenger dedicated railway based on overall calculation method are presented. Its application case in Quzhou Section of the Hangzhou-Changsha Passenger Dedicated Railway has shown that t the design of HPC mix proportion for passenger dedicated railway based on overall calculation method is effective and deserves popularization.
