CONCRETE (B35 MF45) PRODUCED ON MossIA RAILWAY PROJECT

This EPD® refers to concrete fabricated and used by MossIA ANS at the Bane NOR Intercity (SMS 2A) Railway Project. It is a double rail project through and under the municipality of Moss in Norway. It consists of 2 tunnels: under Moss (2.7 km), and from Moss station to Carlberg (2.3 km); Moss Station (800m); 2 significant culverts: Kransen and Carlberg; and 10 km demolition of the existing tracks.

B35 MF45 is produced in two twins Batching Plants located in Granittveien 10 in Våler. It has high quality and durability that will withstand mechanical, climatic and local environmental conditions throughout the life of the construction. It will be used for structures subjected to frost resistance conditions according to the drawings provided by the engineering company. The concrete is assigned with B35 strength and MF45 durability class, which is related to the required maximum water-binder ratio and the frost resistance condition.

All concrete characteristics and tolerances follow the requirements set out in NS-EN 206 Standard. The strength of both was determined based on tests conforming to EN 12390-1 and made and cured in accordance with EN 12390-2 from samples taken in accordance with EN 12350-1; according to NS-EN 206. The life expectancy of the tunnel as well as the studied concrete is at least 150 years taking into account technical requirements specified on the MossIA project.

Regarding to production process, there are two twins independent batching plants to produce concrete for the project. There is also a shed to store the aggregates and protect them against the weather. For producing concrete, all raw materials are mixed on the concrete plant, taking into account dosages determined on laboratory tests. Product produced is trucked to the tunnel for the application
