CO2-Saving Eco-Concrete: ÖBB, Wopfinger and TU Graz prove practicality

The small animal culvert in the course of the double-track extension of the Pottendorf railway line between Vienna Meidling and Wiener Neustadt: The right side was concreted with Eco concrete, the left side with 'normal concrete'. There are no differences between the two types of concrete: Neither in appearance nor in performance. Wopfinger Transportbeton By Christoph Pelzl - For the construction of a small animal culvert in the course of the double-track extension of the Pottendorf railway line between Vienna Meidling and Wiener Neustadt, a concrete mix was used for the first time, whose production emits a quarter less CO2 compared with conventional concrete. When hares, hedgehogs and other small animals cross the Pottendorf line in Ebreichsdorf in Lower Austria, they do so in a very special concrete tunnel, which leads wildlife safely underneath the tracks. This is important because, despite the railway line, there has to be an exchange of animal populations onto both sides of the railway. Otherwise, in the extreme case, certain animal species would disappear. Half of the wildlife crossing near Ebreichsdorf in Lower Austria is made of CO₂-reduced, so-called eco-concrete and half of standard normal concrete.
