The use of structural synthetic fibers as reinforcement can result in significant cost savings in comparison to traditional reinforcement. These savings are achieved in several ways, not only for material and time.
The impact on the environment is also becoming increasingly important in construction. The use of structural synthetic fibers improves the environmental performance of concrete. By using structural synthetic fibers instead of traditional reinforcement, the CO2 footprint of concrete is reduced.
By using constructive synthetic fibers, traditional steel reinforcement can be reduced or fully replaced, which provides a range of technical and cost benefits.
Convez is an independent company belonging to the Scholz Group (Scholz Benelux) and supplier of synthetic fibres (the only ones with a CE-mark!) and concrete technological support.
Synthetic fibres are of the following types:
There are many application areas for synthetic fibres in concrete. Think of floorings, precast elements, infrastructure, industrial floorings, busterminals, stables, agricultural roads, outdoor, harbor quays etcetera.
CONVEZ is the exclusive distributor of the Contec Fiber AG synthetic fibers for the Benelux, Great Britain, Ireland and Canada.
Brugg Contec (Brugg Contec) is part of the Brugg Group (Brugg Group), a worldwide active company, including 20 companies. Brugg produces, among other things, power and telecommunications cables, cables for cranes and cableways, pipes for transport of hazardous substances and nets for avalanches and stone chippings. The Brugg group employs approximately 2000 people. The core competence of Brugg Contec is the production of synthetic fibers. For over 30 years, Brugg Contec is active in the field of plastic fiber technology and the application of synthetic fibers in the concrete.

Saving on reinforcement means cost reduction
Our high-performance fiber Fibrofor High Grade comprises more than 30 years of development and know-how.
The reasons for its outstanding quality are premium-quality raw-materials, the sophisticated production process, the exact fibrillation (which is important for the fast and even distribution in the concrete during the mixing process) and the specially treated surface responsible for the anchorage in the concrete.
Because of all these features 1 kg of Fibrofor High Grade per m3 concrete is able to replace between 20 and 25 kg of steelfibers or up to 40 kg of conventional steel reinforcement.
Based on a project-specific static calculation according to latest standards (Eurocode) our engineers determine whether the steel can be replaced completely or if not how much can be replaced.

Highest strengths including flexural strength
In cooperation with the EMPA Brugg Contec has developed the unique bicomponent, embossed synthetic Macrofiber Concrix. The high E-modulus of the core guarantees the highest strength and the special, structured shell ensures excellent anchoring in the concrete.
Concrix is used as primary reinforcement and increases the impact resistance of the concrete. The way the fibers are delivered (as bundles) guarantees a fast, three dimensional even distribution in the concrete during the mixing process and avoids fiber balls. In addition extensive tests prove the resistance of Concrix against aggressive waters and creeping (long term tested for more than 4 years)!
Based on project-specific data our engineers prepare a static calculation according to latest standards (Eurocode).
