Advantages of UHPC
- Lighter and thin sections
- Extremely Durable due to ultra denseness of concrete
- UHPC doesn’t shrink and minimal creep
- Concrete Grade M-150/165 above
- Span up to 120m, thus reduce foundation cost
- Better Bridge Material compared to conventional (Factory Product)
- Easier Handling & Transport (Lower Tonnage Crane Required)
- Shortened Construction Period (more than 40%)
- With usable structural tensile strength (> 8 MPa) and ductility
- At least 4-6 times stronger than normal concrete (in compressive strength)
- At least 100 times more durable than conventional concrete
- Longer service durability and design life
- Perfect replacement for steel girders
- Cheaper & better solution with significant reduction in cost
- Lower carbon footprint
