Glass Fiber Rebar Debuts

German building materials developer Schoeck Bauteile GmbH has unveiled a glass fiber reinforcing bar, designed to prevent the structural corrosion that plagues steel reinforcement.

Schoeck ComBAR was rolled out last year in the Middle East and has been used across that region and in Europe, the company says.

ComBAR is a ribbed reinforcing bar made of corrosion-resistant glass fibers that are bound by a vinyl ester resin.

Manufacturing is a two-stage process of pultrusion and profiling. In step one, high-strength glass fibers, bundled as densely as possible, are pulled through a closed chamber where they are impregnated with a synthetic resin. In step two, helical ribs are cut into the hardened bars, and the bars are then given a final coating.

Features

According to Schoeck, the material is “much stronger and stiffer than commonly known glass fiber-reinforced polymer (GFRP) bars.” It is also, the company says:

• Highly durable;

• Stronger and significantly lighter than steel;

• Corrosion resistant;

• Non-magnetic or magnetizable;

• Not electrically or thermally conductive; and

• Easily machinable.

Applications

ComBAR has been installed at the Sea Front Restoration Project in Blackpool, England, and at the Royal Villa in Qatar—both highly corrosive environments, the manufacturer says.

Because of its non-conductive and non-magnetic properties, it has also been used in electrical facilities near or below machines operating under high currents, such as transformers and reactors, according to Schoeck. These applications include installation in the floor slab of the rectifier area of the Qatar Aluminum factory and in several reactor buildings in Europe.

ComBAR bars have also been used in tunneling projects, in the areas of concrete diaphragm and drilled pile walls penetrated by the tunnel boring machine, and in railways and other infrastructure projects.

Testing and Certifications

The bars have been durability tested under load at elevated temperatures in moist concrete according to the International Federation for Structural Concrete (fib) testing concept published in its Technical Bulletin 40, the manufacturer says.

ComBAR has been certified in Germany, the Netherlands, the United States and Canada, according to European and North American codes and guidelines. In the Middle East, it has been certified by the Dubai Municipality and tested at The King Fahd University and at the Arab Center for Engineering Studies in Doha, Qatar, according to Schoeck.

Founded in 1962, Schoeck Bauteile GmbH is a family-owned international supplier of reinforcing and other products to the bridge and building industries.
