Mirror surface concrete construction technology of wave wall of Bailianhe Hydropower Station

With the increasing quality demanding on the concrete appearance in architecture,mirror surface concrete appears.Compared with normal concrete construction,higher standards have been requested to appearance quality of mirror surface concrete,these caused more strict raw material quality control,formwork processing technology,concrete placement and curing,concrete defect mending than before.Through the construction of Bailianhe pumped-storage power station in Hubei Province,the complete construction technologies and notice points have been detailly summarized.By strict construction according to the technologies of mirror surface concrete,the concrete architecture with firm internal structure and beautiful appearance can be realized.This paper represents a few measures to reducing the construction costs of mirror surface concrete.
