Fiber Reinforced Concrete Segments For Tunnel Construction: Mix Design, Mechanical Performance, And Engineering Application
Why Tunnel Segments Need Fiber Reinforced Concrete Tunnel segments are not simple concrete products. They must carry ground pressure, water pressure, assembly force, shield jack pressure, transportation stress, and long-term service load. They also need stable dimensional accuracy, reliable joint performance, and good durability. Ordinary reinforced concrete can meet many tunnel lining needs. But in […]
Fiber Reinforced Concrete For Submarine Tunnel Segments: Steel Fiber, Polypropylene Fiber, Crack Control, And Mechanical Performance
Why Submarine Tunnel Segments Need Better Crack Control Submarine tunnel concrete works in a demanding environment. The structure can face water pressure, chloride attack, bending stress, construction load, and long-term service load. A normal concrete mix may have enough compressive strength. But compressive strength is not the only concern for a large tunnel segment. A […]
