摘　　要：为配制性能优越的C60高抛自密实无收缩混凝土,优选最佳粗骨料级配,研究硅灰掺量为0〜12%时对混凝土工作性、抗压强度的影响,选出各项性能优越的配合比,并成功用于逆向项目施工,混凝土浇筑效果良好,各项性能均能满足要求。In order to prepare C60 concrete with superior performance, such as high cast, self compacting and non-shrinkage, optimize the best coarse aggregate gradation, study the influence of silica fume(dosage from 0 to 12%) on concrete’s workability and compressive strength, and select the mixing ratio with superior performance,which has been successfully used in reverse construction. The pouring effect of concrete was good and all properties could meet the requirements.
