The traditional concrete is a very fragile material, resistant to compression, weak to traction.
A very thin and elastic foil allows the wrapping of fibers to reinforce concrete without the use of glue, resulting in small fibers skeins ready to be used and be put directly in the concrete mix. This will reduce the working time and avoid the use of disposable plastic.
The finished product is a reinforced concrete characterised by ductility and toughness.
