Dramix® Steel Fibre Reinforced Concrete: Shotcrete
Enhanced Shotcrete Reinforcement with Dramix® SFRC
Shotcrete, a versatile sprayed concrete, is a crucial element in various construction applications, particularly in tunnels, underground structures, and rock support systems. However, traditional shotcrete reinforcement methods, often using mesh reinforcement, can be time-consuming, labor-intensive, and pose safety concerns. Shotcrete reinforced with Dramix® Steel Fibre reinforcing provides tangible benefits.
Dramix® steel fibre reinforced concrete (SFRC) offers a transformative solution for shotcrete reinforcement, providing a range of benefits over traditional methods:
- Efficient Reinforcement: Dramix® steel fibres, evenly distributed throughout the shotcrete matrix, eliminate the need for mesh reinforcement, significantly increasing installation efficiency and reducing labor costs.
- Enhanced Crack Control: Dramix® fibres effectively bridge hairline cracks, preventing their propagation and minimizing the risk of structural damage. This enhanced crack control is crucial in shotcrete applications where crack resistance is paramount.
- Improved Durability: Dramix® fibres enhance the durability of shotcrete, resisting impact, abrasion, and freeze-thaw cycles, extending the lifespan of the reinforced structures.
- Safer Construction: Eliminating mesh reinforcement reduces the risk of workplace injuries associated with handling and placing heavy mesh elements.
Design Efficiencies with Dramix® SFRC
Dramix® SFRC not only simplifies shotcrete installation but also opens up opportunities for design optimization. The increased bending moment and shear capacities of Dramix® SFRC allow for thinner shotcrete sections without compromising structural integrity, leading to material savings and reduced construction costs.
Combined Reinforcement for Watertight Shotcrete Linings
In situations where a watertight shotcrete lining is required, Dramix® SFRC can be used in combination with conventional reinforcing. This combined reinforcement approach often allows for the reduction of reinforcing layers, typically from two to one, while simultaneously enhancing crack control and eliminating expensive water stopped joints.
