| Abstract: | 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. |
