Application of
Bridges And Overlay
STRENGTH, DURABILITY AND LOW COST OF CONCRETE STRUCTURES
FAST AND DEPENDABLE REINFORCEMENT IN BRIDGES AND OVERLAYS CONSTRUCTION.
The steel fiber inclusions are provided to minimize the initial formation and progressive propagation of drying shrinkage cracks and micro cracks. SFRC is ultra high-strength concrete with unique properties including high flexural and shear strength. It is also strong in compression, durable and has high impact resistance. The fibres have increased the load-carrying capacity of the externally bonded ties by approximately 70%. Similar results were obtained for the beams reinforced with steels bars: the bearing capacity was increased by almost 25%

BENEFITS
Increase reinforcement effects with wall of even thickness on a rugged surface
Increase tensile strength, bending strength, shear strength of concrete; no hollowing-out ; reduction of wall thickness(20%)
High resistance to cracking; increase in toughness (residual strength) after cracking Shotcrete construction possible right after excavation; drop in risk of cave-in disasters; rise in reinforcement effects and safety of permanent structures
COST EFFECTIVENESS
Reduce labor costs, as no reinforcement assembly process is required Reduce working hours and construction costs
Reduce construction cost due to shortened construction period.
Reduce working hours and construction costs.
QUALITY
