The superplasticizers Glenium® 27 and Rheobuild® 850 were used to modify the concrete for bridge construction, while concrete repairs were carried out using Emaco® S88 C and Emaco® R303. Masterflex® waterstop tape and Masterseal® 550 were used for waterproofing the tunnels, Concresive® 1414 for connecting precast concrete parts and Flowcable® grout for fixing anchor bolts. Rheofinish® 202 provided a smooth surface for the precast concrete parts, and superplasticizers with air-entraining agents Microair® 120 and Microair® 111 along with the evaporation protection agent Masterkure® 106 secured a high level of concrete quality. MEYCO® SA 160, an alkali-free accelerator for sprayed concrete, helped stabilize tunnels and slopes.
