Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications
Structural Concrete, EarlyView.Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...
