摘要：
This study examined the durability of face slab concrete in Concrete-Faced Rock-filled Dams (CFRDs). The durability of face slab concrete can be improved by optimising the amount of fly ash in the cement mixture. Durability tests, including permeability, abrasion resistance, adiabatic temperature rise and repeated freezing and thawing, were conducted for face slab concrete using different amounts of fly ash and PVA (Poly Vinyl Alcohol) fibre. When the effect of the fly ash content on the concrete durability was evaluated, the results showed that a 15% fly ash content and a 0.1% PVA fibre yielded the most effective durability level for CFRDs.
