摘要：

The main purpose of this research was to enhance the durability in both the design and construction of dams. Especially, in case of rockfill dams, the durability of face slab concrete in a concrete-faced rockfill dam (CFRD) is achieved by optimizing the fly ash replacement for cement. The effect on durability corresponding to the increasing replacement of fly ash was evaluated, and the optimum value of fly ash replacement was recommended. The results show that 15% of fly ash replacement was found to be an optimum level and demonstrated excellent performance in durability. (C) 2002 Elsevier Science Ltd. All rights reserved.
