ArcelorMittal awarded for innovative concrete dowel technology

Munich, 22 January 2015 - ArcelorMittal Europe – Long Products is awarded by the German steel construction industry for the development of “CoSFB-Betondübel”, an innovative concrete dowel technology. This innovation is part of the design of CoSFB (Composite Slim-Floor Beam), a new ingenious floor beam. The prize ceremony took place on 20th January 2015 at the fair BAU 2015 in Munich.

The development of CoSFB-Betondübel

The development of the integrated floor beam was initiated by ArcelorMittal’s Technical Advisory team in Esch-sur-Alzette, Luxembourg (Matthias Braun and Dr Oliver Hechler). Key of this success story was the close collaboration and the early involvement of ArcelorMittal Construction France (Vincent Birarda) and ArcelorMittal Global R&D, Esch-sur-Alzette (Dr Renata Obiala, Dr Olivier Vassart).

Consensus about the current and future market demand was quickly leading to the decision to develop a new shear connector for integrated floor beams, the CoSFB-Betondübel.

Thanks to an immediate project launch, first test results were already available after six months. This enabled a direct implementation of the new technology in first reference projects. The parallel improvement and development of slab elements - Cofradal 260 and Cofraplus 220 - completes the product portfolio and provides sustainable and economic floor solutions.

The integrated floor beam is a sustainable solution for European markets and fills a gap in the construction sector - the deployment of this concept has started. References already exist in Luxembourg and France. Since August 2014, a National Approval for CoSFB-Betondübel is available for the German market and the technology is prescribed in first construction biddings.
