Steel fiber reinforced concrete (SFRC) used in bridge deck pavement offers significant benefits in terms of improving crack resistance, wear resistance, and reducing maintenance workload. The advent of steel fibers represents a revolutionary change in concrete technology that can be compared to the impact of reinforced concrete and prestressed concrete. This innovation has profoundly transformed traditional construction material techniques.
Steel fiber reinforced concrete is made by uniformly mixing an appropriate amount of carbon steel fibers into ordinary concrete. Its main characteristics are:
High bending, shear, and impermeability strengths.
High crack resistance, low shrinkage, effectively preventing the occurrence of cracks.
Significant improvement in toughness.
Steel fibers can be uniformly distributed within the concrete, reaching the ends of the group without exposure.
Significantly improved impact resistance.
The maintenance of steel fiber reinforced concrete is the same as that of ordinary concrete.
Economic and Social Benefits
From an analysis of economic and social benefits, compared to ordinary cement concrete pavement, steel fiber reinforced concrete pavement offers the following advantages:
1.Reduced thickness of the bridge deck pavement, shortened construction cycle, increased spacing between shrinkage joints, saving raw materials, and reducing project costs.
2.Extended service life of the bridge.
3.The mixing process of steel fiber reinforced concrete is not significantly different from that of ordinary concrete, requiring no additional specialized equipment.
4.Allows for earlier traffic opening.
A comprehensive analysis of the economic benefits of steel fiber reinforced concrete, considering one-time investment, service life, maintenance costs, and the time value of money, shows that although the initial investment is higher, the reduced maintenance costs, extended service life, and overall time value make the use of steel fiber reinforced concrete highly beneficial economically and socially.
Conclusion
Since its development, steel fiber reinforced concrete has been widely used in highway pavements, bridge decks, airport runways, and more. It has achieved significant economic and social benefits. In addition to its excellent bending strength, it also offers outstanding impact resistance and crack resistance.
