武合客运专线耐久性混凝土配合比优化设计与施工要求

Optimization and Construction of Durable Concrete Mix for Bridges,Culverts and Girders of Hefei-Wuhan Passengers Dedicated Line

以合武客运专线I标特大桥、大桥、涵洞、隧道、连续梁耐久性混凝土配合比设计为例,介绍了耐久性混凝土原材料的选定、配合比的优化设计理念,阐述混凝土耐久性配合比试验过程及优化设计效果。

The newly built Shanghai -Chengdu Railway Line is the first PDL in China where the durable concrete is adopted. Taking an example of durable concrete mix design for the super-large bridges,major bridges,culverts,tunnels,and continuous beams in Section I of Hefei-Wuhan PDL and based on the raw materials selection,mix ratio optimization plan, test data of durability,as well as construction process and reasoning of read project,this paper expounds briefly the design and construction of concrete durability mix ratio.
