Bi-component mortar for Follo Line Project Railway Tunnel

Bi-component mortar is a bonding material that integrate construction materials into a single element. Mortar must be strong, durable and capable of keeping the wall intact. Mortar also must help to create a water resistant barrier. In the case of the Follo Line Project, wherein the object is the construction of the 20 km long tunnel, the Bi-component mortar is used to fill the space between tunnel concrete elements and drilled rock, regardless of mixing ratio. The life expectancy of the tunnel as well as the studied bi-component mortar is at least 100 years.
