Performance of Reinforced Concrete with Polymeric Macrofibers and Graphene Oxide:Results Report Graphenergy® Construction

Polymeric macrofibers are small filaments of strong synthetic material dispersed throughout the concrete mix to reinforce it from within. Their random distribution creates a discontinuous and homogeneous three-dimensional reinforcement effect that enhances the concrete’s toughness and ductility at every point of the structure. 

The materials commonly used for the manufacture of this type of product include polypropylene, polyethylene, polyester, or nylon in different gauges or dimensions. These are highly effective for the reinforcement of pavements and roads, slabs, precast elements, shotcrete, and in some cases, may even substitute welded wire mesh. Given the wide variety of products, it is important to seek proper advice before use and to consider that macrofibers do not always increase the compressive or flexural strength of concrete, as they are mainly used for microcrack control. Therefore, they are not intended as a full replacement for structural reinforcement such as steel. 

The Mexican company Energeia–Graphenemex®, through its polymer division, integrated the multifunctionality of graphene oxide to launch Graphenergy® Polymeric Macrofibers in order to enhance concrete performance under intense stresses. 

Graphenergy® polymeric macrofibers represent an innovation in secondary three-dimensional reinforcement for concrete thanks to the integration of polymers and graphene oxide in their formulation. Unlike conventional fibers, the nanotechnology-based design and wavy surface of these macrofibers significantly improve their performance within the concrete.
