A sluice gate is a hydraulic structure that controls flood water, affords protection against tides, and channels and stores water. Its operation and management is fundamental to ensuring the safety of the lives and property of the general public. The number of sluice gates across Taiwan has been increased since the government performed improvement works on river drainage canals and flood-prone detention basins and pumping stations. Sluice gates in Taiwan are mostly made of metal (including cast iron, black iron, and stainless steel); they are frequently stolen and sold as scrap metal because global metal prices continue to rise, pushing scrap metal prices higher. Such thefts are more common in sparsely populated regions [1]. An additional problem is that bulky steel sluice gates make it difficult to discharge water inside of levees. Malfunctioning sluice gates inhibit efforts to prevent floods, thus threatening public safety and property. This underlines the need to develop nonsteel sluice gates that have lower dead weight, are less likely to be stolen, and can facilitate water discharge. Concrete is characterized by high strength, density, durability, and modulus of elasticity and low permeability and cost; it also weighs much less than steel. Fiber-reinforced concrete (FRC) is a composite concrete material containing uniformly distributed fibers whose high tensile strength helps to prevent the material from rupturing internally and enables it to withstand the extension of cracks. FRC is thus stronger and more resistant to cracks, impacts, shocks, and abrasion than normal concrete [2–۵]. In the present study, concrete was used to construct sluice gates, the mechanical properties, durability, and cost of which were assessed. The findings of this study can be applied in hydraulic engineering.
