Abstract: The Citytunneln project is the connection between the Öresund Bridge and the Central Station of Malmö. The concrete had to be designed for a life time of 120 years. Based on this a huge test program for all concretes in this project was necessary and a lot of requirements had to be fulfilled. This paper gives an overview of most of the tests that had to be done for the SCC.
For the pillars and beams of the Station Triangeln in the centre of Malmö, SCC was used.
The number of requirements has made the mix design development difficult and led to a complex recipe. Special attention had to be drawn on the fire resistance, PP-fibres were used to fulfil the requirements. For the design of the formwork a formwork pressure test was carried out with the intended recipe during a test casting of a Pillar with a height of 7 m. The maximum pressure was app. 65% of the hydrostatic pressure. At the end 1.700 m³ of self compacting concrete have been cast successfully.
