C60盾构式管片高性能混凝土配合比设计的研究

A Study on the Mix Design of C60 Shield Segment High Performance Concrete

结合南京纬三路过江通道工程N线工区C60盾构式管片高性能混凝土的制备要求,对C60高性能混凝土配合比进行了系统研究,提出C60盾构式管片高性能配合比参数的控制以及一种简易的配合比优化设计方法,应用中取得较好的效果。

Combined with the production of high performance concrete with C60 shield segments in the working area Line N of the cross-river tunnel project on Nanjing Weisan Road,this thesis conducts a systematic research on the mixing ratio of C60 high performance concrete.Based on the specific requirement of segment quality for cross-river tunnel,this thesis also proposes a method for controlling ratio parameters and a simple method for optimizing mixing ratio design of C60 high performance concrete.Both of them have achieved good results in application.
