Reinforce safely without steel. Schöck ComBAR®.

For decades, steel rebar has been commonly used as the reinforcement in concrete construction. Despite its strength, steel is not the ideal solution for reinforcement especially in corrosive and electromagnetically sensitive environments. In these cases, our innovative product, Schöck ComBAR® presents advanced possibilities and unique solutions.

Healthy construction with Schöck ComBAR®

Caused by its electrical conductivity, construction steel can allow an uncontrolled electrical current flow in the reinforcement. Electrical as well as magnetic fields, that come from conducting cables create an interface to the steel reinforcement and can be carried through the entire construction. To create a healthy living and working environment, the task is to avoid harmful burdens like electromagnetic pollution in the house and building that can affect people's health. ComBAR® could be the solution for that. The product is neither electrically conducting nor magnetizable. Therefore the natural geomagnetic field remains unaffected. Schoeck ComBAR® is the ideal, ecologically proven and certified alternative to construction steel.

Infrastructures often have to be repaired or replaced because the steel reinforcement within them has corroded destroying the concrete microstructure. This particularly applies to bridges exposed to de-icing salts. When Schöck ComBAR® is installed, corrosion problems are eliminated. New high speed rail links and streetcar lines are usually built using ballasted rail slabs. The continuous rails serve as an electrical medium for the signal transmission. The reinforcing steel in the rail slabs must be intricately grounded to allow the undisturbed transmission of these signals. When Schöck ComBAR® is installed, these grounding measures are unnecessary as the bar does not conduct electric currents. It may even be installed in close proximity to the induction coils used to operate rail switches.

Transformers and reactors in power plants, switchyards and industrial facilities (steel mills, aluminum smelters etc.) operate with high electric currents. Inductive currents are generated within the reinforcing steel if it is located too close to these coils. This can result in the heating up of the rebars and a loss of their strength. To avoid this, steel reinforced concrete elements must not be located within the magnetic clearance contour of these coils. ComBAR® bars do not conduct electro-magnetic currents. Therefore, ComBAR® reinforced foundations, walls and ceilings can be built near transformer coils and reactors. As a result, enclosures for these coils can be much smaller without hindering the performance of these machines. This significantly reduces construction and operating costs.

Research laboratories for nanotechnology, solid state physics and similar fi elds of research are highly sensitive environments. This is also true for scanning electron microscopy, magnetic spin tomography and magnet resonance tomography. Due to its conductivity, reinforcing steel can aff ect the functionality and precision of these devices. The installation of Schöck ComBAR® creates a completely non-metallic and non-magnetic research environment.

The most frequent cause of damage in reinforced concrete buildings is the corrosion of the steel reinforcement. This is especially true of facade components, buildings in coastal areas, bridges and parking garages exposed to de-icing salts, as well as swimming pools, waste water treatment plants and many other industrial facilities. As Schöck ComBAR® does not rust, the risk of corrosion damage is eliminated resulting in the signifi cant reduction in repair and maintenance costs. Also, the service life of the building is greatly extended - an important contribution to sustainable construction.

Inner city tunnels for subways, sewers and other infrastructure facilities are usually built using a tunnel boring machine (TBM). Steel reinforcement presents a problem as the TBM cannot drill through the steel reinforced shaft walls. When the walls have to be opened up manually, the soil behind these walls has to be stabilized. The installation of Schöck ComBAR® in the penetration area of the TBM makes all these measures unnecessary. The TBM drives and cuts directly through the head wall. Construction time and costs are greatly reduced and job site safety is also significantly improved.
