摘要
通过对不同种类和不同掺量的矿物掺和料配合比室内拌和结果对比分析,得出粉煤灰、矿渣粉各掺加20%时混凝土耐久性能、力学性能及其他性能满足设计使用100年的要求,可以用于京沪高铁墩身、承台等施工部位的施工。通过对混凝土原材料拌和、浇筑及养护的控制,高性能混凝土得到了成功应用。
Through comparison and analysis of indoor mix test result of different kinds of mineral additives,we obtained that concrete with 20% fly ash and 20% slag powder can meet the requirement of working life of 100 years,which may be used for piers and caps of Beijing-Shanghai high speed railway.With control of raw material mixing,pouring and curing,the high-performance concrete can be applied successfully.
