Porr patents slag-based mortar used in Filder Tunnel project

Austria/Germany: Austria-based Porr says it has used a new annular gap mortar bound with granulated slag, instead of cement, on the Filder Tunnel stage of a project for Deutsche Bahn near Stuttgart. The engineering company reports that the pilot project was a success and the ‘practically cement-free construction material’ has already been patented. Porr is now looking for further cooperation partners.
“The nature of the soil means that a cement-based construction material would not have been suitable,” said Porr’s chief executive officer Karl-Heinz Strauss. “This gave us the opportunity to use this brand new construction material”. He added, “Apart from allowing us to contribute to reducing CO2, this construction material has two fundamental advantages. It is less sensitive to environmental factors than concrete containing cement. And it can be transported for long periods without any problems before it is processed as it needs an activator to fully harden”.

Austria: Rail logistics company ÖBB Rail Cargo Group (RCG) says that its haulage of 80,000t/yr of granulated blast furnace slag (GBFS) and clinker to and from w&p Zement's Wietersdorf cement plant in Carinthia by rail has removed 3200 trucks/yr from the road since its start in 2019. RCG's trains deliver the plant's clinker to the Peggau-Deutschfeistritz railway station in Styria, and return to the plant laden with GBFS from steel producer Voestalpine's nearby Leoben refinery.
RCG said that w&p Zement is currently working to increase its operations' reliance on rail, adding "Further innovative transport solutions are already being worked on."
