【Abstract】 In this paper, the measures for elevating the crack resistance, impermeability and durability of concrete for face\|plate in CFRD, 200m in height, are experimentally studied. The results show that the adoption of triple composite additive, Grade I fly\|ash, siliceous power and relvant agent for enhancing its strength, synthetic fiber as well as steel fiber are effective in improving the properties of concrete.更多还原
