Project DescriptionA new production plant for Mercedes-Benz has been built in the Hungarian city of Kecskemét. A cooperation agreement between the Hungarian government and Mercedes Benz for the construction of the new plant was signed on 27 October 2008. The foundation stone was laid on 16 October 2009. The investment for this new plant will be approximately 800 Million Euro and will create around 2,500 new jobs. The production capacity of the plant is approximately 100,000 cars per year. In association with the plant in Rastatt, two vehicles from the next generation of today’s A- and B-Class are to roll off the production line in Kecskemét from 2012.The plant includes a welding shop, assembly and logistics halls, a paint shop, a central administration building, and various outbuildings. The total area of the facility is 441 hectare. The plant area itself will be 310,000 m2.

Project RequirementsThe Tender for structural work was won by two construction companies, Strabag Co. and KÉSZ Ltd. Concrete for KÉSZ Ltd was produced by CEMEX and TBG. Sika Hungary Ltd participated in the project as a concrete admixtures supplier for those concrete plants, which produced a total of 48,000 m3 of concrete.The concrete has to be designed for various applicationsn Base slabn Internal wallsn Industrial floorsn Columns

The flow class was defined as F3 and a workability retention time of 90 minutes was required. Due to the characteristics of the raw materials, especially the sands, the required workability time of 90 minutes was a real challenge. In the first trials the loss in workability was very high but this was significantly improved by the incorporation of Sika ViscoCrete 4025 Ultra. Furthermore the concrete has to meet various exposure classes e.g. exposure class for wear resistance in Hungary (XK1 (H)) and Corrosion induced by carbonation (XC1)


Sika SolutionsThe use of the new Sika® ViscoCrete® 4025 Ultra created a good quality concrete and the workability retention time requirement could be fulfilled. Sika® ViscoCrete® 4025 Ultra is based on Sika’s new ViscoFlow PCE Technology. The ViscoFlow polymers are designed to maintain consistent workability over a specified time period. The Sika® ViscoCrete® 4025 Ultra also performed very well in all weather conditions.
