Carbon reinforcement available in much greater dimensions

Concrete withstands compressive loads excellently, but is susceptible to tension. For this reason, concrete has been combined with steel in the construction industry for decades. Steel absorbs these tensile forces, but it has a major weakness: it corrodes. In order to prevent this, steel has to be provided with an adequate concrete cover. In case of carbon-reinforced concrete, the steel reinforcement is replaced by carbon fibers. This gives rise to lot of advantages: Since carbon fibers do not corrode, the usual concrete cover can be realized considerably thinner. This means that building components can be more lightweight and slenderer.

Besides, among others, less cement, water and sand are needed which is not only economical but also contributes to a positive environmental track record. In addition, the weight of the actual carbon reinforcement is much lower than that of steel reinforcement. This simplifies its application enormously. And building with carbon-reinforced concrete is a big benefit in the long run, too. Since the reinforcement does not corrode, building structures made of carbon-reinforced concrete require extremely low maintenance. This grid reinforcement made of carbon fibers has recently been offered by Solidian in much greater dimensions than previous grids.

 

Larger meshes

Over a five-year development period, the manufacturer managed to develop a production procedure for manufacturing an even more efficient carbon-fiber reinforcement. This reinforcement is called Solidian Grid and will revolutionize construction, according to information of the manufacturer. The procedure serves the production of carbon mesh, which is primarily intended for applications in the precast plant but can possibly be of useful service at the construction site too. The new technology will replace the currently widely used manual production of reinforcement meshes and allows standardizing their production.

Since May 2020, the reinforcement meshes made of carbon fibers have been available in a convenient standard mesh size of 2.3 m x 6.0 m thanks to the new plant. The maximum dimensions are 3.0 m x 8.0 m, and the product also offered in roll form will have a length of up to 80 m in future; an enormous increase in comparison to the present sizes. As a consequence, the number of mesh joints will be reduced considerably. Hence, there are even two advantages: On the one hand, less material has to be used – as overlapping areas are reduced. And, on the other hand, the work process is much faster – as there are fewer spots where the reinforcement meshes need to be tied together.

 

Increased performance

The mean breaking stress of conventional carbon mesh accounts for approx. 3,200 N/mm², with a deviation of approx. 10 %. Whereas the new Solidian Grid has a mean breaking stress of more than 4,000 N/mm². Moreover, the deviation can be minimized, amounting to approx. 5 % now. This corresponds to a performance increase of more than 25 %. As a result, the grid spacings of the reinforcement can be larger or the actual reinforcement can be designed thinner.

 

Individual production

Solidian offers the Solidian Grid as prefabricated mesh and in roll form, respectively, or manufactures the reinforcement individually, upon request. In the latter case, the company caters to the specific requirements of the client. This also allows manufacturing shaped reinforcement such as L-shaped or U-shaped profiles. A team of experts provides for a smooth changeover from steel reinforcement to carbon reinforcement and instructs the workers on site.
