Abstract:
Abrasion erosion in concrete hydraulic structures is a common problem which reduces the service life of the structure. Ultra-High-Performance Concrete (UHPC) is a new class of concrete known for its superior durability, strength, and ductility, along with enhanced abrasion resistance compared to Normal Strength Concrete (NSC) and High Strength Concrete (HSC). The typical mix for UHPC includes cement, silica fume, fine sand, fibers, and a very low water-to-cement (w/c) ratio. While the abrasion resistance of UHPC has been investigated under various flow conditions, the impact of varying paste content and fiber dosage remains unclear in the literature. This study focuses on the abrasion resistance of UHPC with different fiber dosages while maintaining a constant paste content. The abrasion tests were conducted following ASTM C1138. The results indicate that abrasion resistance decreases as fiber content increases.
