BASF: Top performance with Master Builders Solutions

Sports stadiums are major construction projects that normally need to be completed under considerable pressure of time and pose a variety of challenges. “These include the concreting of large areas in city centers, the harmonization of design and safety standards and the construction of grandstands, roofs and parking areas that can BASF SE withstand wind and weather”, explains Dr. Michael Fischer, responsible at BASF for regional market management for concrete additives in Europe. “These challenges can be mastered extremely effectively using the broad product portfolio and flexible solutions of Master Builders Solutions.”

This has recently been demonstrated by projects throughout Europe. Projects completed using these solutions include the Warsaw National Stadium, the Aviva Stadium in Dublin and the San Mamés football stadium in Bilbao, northern Spain. These stadiums all offer seating for more than 50,000 spectators at sports and cultural events. In addition, for the current construction of the Allianz Stadium in Vienna precast concrete from Master Builders Solutions was used.


Face concrete for 9 km of grandstands

Work on the construction of the Allianz Stadium in Vienna started in February 2015. The new stadium, which is to be ready for the 2016/17 season, is to offer space for more than 24,000 spectators. Concrete admixtures from Master Builders Solutions were used for the prefabricated concrete components of the 9 km of grandstands. This project called for a self-compacting concrete (SCC) with high segregation resistance. For this reason, the experts from Applications Technology optimized the concrete formulation with MasterGlenium ACE 430. This concrete admixture promotes the fine dispersion of the cement and is therefore suitable for the production of self-compacting concrete. “This type of concrete is especially economical as faster construction reduces time and energy requirements and also means that less personnel is required”, says Thomas Strobl, Technical Services Admixtures. “Deadlines can be met reliably and the construction progress becomes more predictable.”

Appearance was a key factor for the construction of the grandstands. The exposed concrete surfaces were to be free from air inclusions and pores and to show uniform coloring. These objectives were achieved thanks to the use of MasterFinish DF 370. During concrete mixing and placing, this product functions as a “de-aerator”, preventing air bubbles forming on the shuttered concrete surfaces. As a result, it is possible to produce exposed surfaces without pores.


Concrete construction in all weather conditions

The Warsaw National Stadium had to be completed to a tight time schedule as it was needed for the 2012 European Football Championships. No significant interruptions were scheduled and 220,000 m³ of concrete had to be placed at high and low temperatures. Concrete admixtures were required to ensure homogeneous consistency in different weather conditions. The ideal solution was provided by water reducing admixtures from the MasterGlenium series in combination with MasterPozzolith for high ambient temperatures. These products ensured optimum concrete quality in all weather conditions.


A solution package from a single source

The objective in the construction of the San Mamés Stadium was to involve as few suppliers as possible in order to minimize the complexity of the project. Experts from Master Builders Solutions provided a complete solution package ranging from concrete admixtures to waterproofing products. They prepared a detailed manual for the use of these products, which simplified construction work and ensured completion on schedule in August 2014.

Concrete plasticizers from the MasterGlenium SKY series ensured smooth and trouble-free concreting. The strong point of this product is the precise adjustment of concrete properties and the ability to maintain workability up to installation on site. The bleachers were waterproofed with MasterSeal, an easy-to-apply membrane with high elasticity. The membrane features good crack bridging properties and prevents water from entering the structure.


A stadium with a long history

Time was also of the essence for work on the Aviva Stadium in Dublin: as the world’s oldest rugby stadium it is located in a quiet residential district, the construction of the new stadium was to be completed as rapidly as possible without any adverse effects on local residents. It was intended to use waterproof concrete for the northern stand. A MasterPel admixture was put to good use in order to obtain water-repellent properties. Together with MasterGlenium as a plasticizer, this product ensures a surface with strong, durable hydrophobic properties. Concrete pores are reduced and the remaining pores received durable water-repellent properties.

Throughout Europe, the broad Master Builders Solutions product portfolio has proven to be beneficial for complex projects such as the construction of stadiums. “Customers benefit from the broad experience and the connectedness of our experts in Europe and they receive a comprehensive package of services and intensive advice”, says Michael Fischer. “This simplifies the construction process and ensures timely completion even of time-critical projects.”
