Swiss Federal Railways (SBB)
Gotthard
Swiss Federal Railways (SBB) have installed Dramix® reinforcement fibers in the Gotthard base tunnel, the world's longest rail tunnel. The Gotthard Base Tunnel was officially opened in 2016, after 14 years of work by Swiss Federal Railways (SBB). At 57.09 km, it is the longest railway tunnel and the deepest traffic tunnel in the world, as well as the first flat, low-level route through the Alps.
The use of Dramix steel fibre in shotcrete has enabled CO2 emissions to be reduced by 50 to 75% compared with the use of traditional reinforcement methods. This is due to the material and labour savings achieved by using steel fibre, the reduction in the quantity of concrete to be transported thanks to automation, and the optimisation of the design mix.
Dramix® steel fiber reinforced concrete offers a solution that is both effective, cost-efficient and environmentally conscious. By using steel fibers instead of traditional concrete reinforcement methods such as mesh or rebar, you can reduce the CO2 emissions by up to 35% for the construction of, for example, an automated warehouse, a production plant, tunnels, precast elements, etc. This is because steel fibers reinforce concrete homogeneously, requiring less material for the same level of performance. Additionally, advanced design optimization allows for the creation of thinner, yet durable concrete elements that use less concrete, steel, and water compared to traditional reinforcement methods.
