The future of concrete reinforcement – fiberglass rods replacing steel?

CG Tec produces two fiberglass rods, G Tec Bar and G Tec Bar Lite, that offer a technical alternative to traditional steel reinforcement in concrete structures.

G Tec Bar is a continuously formed, fiberglass-based reinforcement bar designed for demanding applications in the construction sector. The material offers high mechanical strength and strong resistance to moisture and chemical influences. Since it contains no iron, the bar will not rust and therefore requires no corrosion protection. This makes it suitable for demanding applications such as bridges, tunnels, or exposed concrete structures. G Tec Bar Lite adds a more economical solution to the product portfolio for simpler applications. The lightweight fiberglass rod provides the necessary composite effect and is suitable for foundations, non-load-bearing walls, or slabs.

"We want to make the introduction to concrete construction using fiberglass composite materials as easy as possible," said Daniel Kipf, Commercial Director at CG Tec.

Both reinforcement bar types are lightweight, reducing the physical burden during laying and shortening installation time. Furthermore, this lightweight design improves CO2 emissions during transportation to the construction site.

The carbonbeton24.de platform offers new reinforcement solutions. Both reinforcement rods can be ordered through the associated online shop, "Carbonscout." Additional carbon fiber, basalt, and natural fiber versions are in the pipeline.

Both versions comply with the new DAfStb guideline "Non-metallic Reinforcement." Effective January 2024, this guideline provides reliable rules for the calculation and design of fiber composite reinforcements. This allows fiber composite reinforcements to be planned and used in accordance with legal requirements and standards.

According to the company, additional versions based on carbon fiber, basalt fiber, and natural fibers are in development. Each offers advantages in terms of performance, sustainability, and resource efficiency. Carbon fiber offers particularly high strength and stiffness for demanding structural solutions. Basalt fiber versions utilize its natural properties and are both strong and economical.
