New national stadium in Bratislava

Bratislava - Slovakia

The Štadión Tehelnépole, which roughly translated means “Brick Field Stadium”, has been designed as a soccer venue that corresponds to the highest possible UEFA stadium category of 4. This makes it suitable for international matches, as well as European and Champions League games. It is currently being erected at a cost of around 75 million euros on the same site as the old stadium, which was demolished in 2013. The clients are the Slovak state and the local soccer club Slovan Bratislava, which will play its home matches at the National Stadium in the future.
Structure made of precast components

With preparatory work on the construction site commencing as early as 2016, production of the stadium's precast elements began in 2017. The new building is made entirely of precast concrete components, almost all of which are one-offs. The client specifications are aligned not only to functional quality but also to ensuring the highest aes-thetic appeal of the concrete surfaces. The Slovakian subsidiary of STRABAG SE, based in Bratislava, won the tender for the production of the prefabricated parts and consulted MC's concrete technologists for formulation development.

Getting the right mix

Included in the concrete to ensure the required properties, MC-PowerFlow 3130 is a high-performance superplasticiser based on the latest MC polymer technology. Through accelerated adsorption at the binding agents, its liquefying effect sets in after just a short mixing time. MC-PowerFlow 3130 is free of corrosion-promoting components, enables above-average water savings and promotes early strength development, enabling high-density and high-quality surfaces to be quickly achieved.  

The new national stadium in Slovakia consists entirely of precast concrete elements manufactured with high-performance superplasticisers and release agents from MC.

With these advantages, MC-PowerFlow 3130 is perfectly suited for the production of exposed concrete surfaces and high-performance, high-resist-ance and high-resilience concretes. However, it is in the production of precast components that it really comes into its own.
Superb surfaces

Exceptional results have been produced by the interaction of MC-PowerFlow 3130 with the concrete release agent Ortolan Premium 702, which has been specially developed for the production of high-quality exposed and fair-faced concretes of grades SB 3 and SB 4. Ortolan Premium 702 can be used on smooth, non-absorbent formwork and heated formwork up to 80 °C. It is easy to spray and forms a thin film on the surface. It also protects and helps maintain steel formwork. Thanks to its excellent release effect, Ortolan Premium 702 reduces pores and cavities to leave a surface of exceptional quality.
MC's concrete cosmetics are also being used on the construction site. This ensures that any small defects occuring during transportation or assembly are quickly and effectively rectified. The aim is to create an appealing overall visual effect that will delight both the clients and future spectators in equal measure.
