According to construction site condition and requirements on construction schedule, the performance of roller com-pacted concrete( RCC) of Zhentouba I Hydropower Station was studied thoroughly, and the substitution of roller compacted con-crete for mass normal concrete at foundation part was proposed, through which the construction schedule was promoted and invest-ment was reduced. The key technical issues in application of roller concrete were researched. The application show that the RCC could solve problems of placement strength, temperature control, layer division and block division, thus promoting construction process and controlling investment.
