Process Technology

The reinforcement of flat and slender concrete structures is possible efficiently and cost-effectively using prestressed carbon fabrics.

For this purpose, the carbon fabrics are provided with anchor bodies made of plastic or mineral end pieces, which are inserted into so-called metallic grippers. By holding the scrims in the grippers, the scrim strip can be prestressed to the breaking point. Targeted prestressing of this filigree structure is thus possible. The prestressing of the fine roving structure in the concrete matrix is possible without problems in the immediate bond and with high load concentrations, even with very short anchorage lengths and thus close to the support.

In general, it is possible to use these strip-like prestressing fabrics in several directions, so that crossing prestressed panels are also possible.

However, the concrete matrix should be limited to 0/2 grain size for strands consisting of 1 - 2.5 cm spaced warp rovings in order to achieve a good bond between the concrete and the prestressed strand structures.


Pre-stressing: Based on patents of the company Ginkgo Projektentwicklung, industrially manufactured pre-stressed concrete elements can be further processed.

Corrosion resistance: Through tensile reinforcement made of carbon fiber.

Lightness: The use of high-strength carbon fiber eliminates the need for a large concrete cover, which is common in reinforced concrete. Very thin-walled components can be produced.

Energy and resource saving: Over 70% less weight than reinforced concrete: This also means lower energy and material consumption. And that with the same load capacity!

Approval procedure in individual cases: Necessary, since no standard yet regulates the state of the art.
