摘要
Abstract
In this paper,the wall lining around the flood discharge and spillway tunnel of Lawa Hydropower Sta-tion was taken as the research object.Through technological tests,the influence of different formwork materi-als,different vibration parameters and different release agents were compared on the appearance quality of mir-rored concrete.The results show that:The appearance quality of mirror concrete can be effectively improved by using single-sided polished steel plate or composite steel plate as template,using salad oil as release agent,and using vibration parameters of 60 s for initial vibration,45 s for re-vibration,and 20 min interval.Optimi-zing vibration process and strengthening quality control during construction play a key role in the appearance quality of mirror concrete.关键词
