re-bar

re-bar in cemetitious matrix

re-fer is producing Fe-SMA bars of re-bar with diameters of 10, 12 and 16 mm. Pre-strained and cut in our facility, the steel bars can be delivered directly to the construction site. They can easily be installed and activated with re-fer´s heating device. re-bar can be applied in concrete structures instead of conventional reinforcement and prestressing steel. Two strengthening systems are offered for retrofitting: the application in shotcrete re-crete, as well as in the cementitious grout/mortar re-grout.

re-bar in shotcrete re-crete

The concrete surface is roughened, the re-bar fixed and embedded in shotcrete re-crete for overhead applications. The required minimum cover is in the range of 0.5 to 1.0 cm due to the good corrosion resistance of re-bar.

re-bar in re-grout

For negative bending moment strengthening, re-bar is placed into a groove in the concrete, which is backfilled with the self-levelling mortar re-grout. The required minimum cover is in the range of 0.5 to 1.0 cm due to the good corrosion resistance of re-bar.
