CONSTRUCTION INNOVATION

Graphene oxide as the differentiating Nanoadditive for concrete.

Graphene, like diamond and graphite, is a carbon-based material. However, it distinguishes itself by being two-dimensional (2D), consisting of carbon atoms arranged in a hexagonal pattern with just one atom thickness.

Graphene Sheet

There are two general types of graphene

Graphene

Graphene is an hydrophobic and conductive nanostructure.

Its handling is more complex. due to its difficulty to combine with other molecules; chemical functionalizations are often required.

Graphene Oxide

Comprises a graphene like material modified with oxygen molecules.

Is usually a hydrophilic and nonconductive nanostructure, easily combinable with other materials or molecules.

graphene PROPERTIES

Graphene can act as an insulator, semiconductor, or conductor, with up to 10 times the conductivity of copper or aluminum.

Graphene is an excellent thermal conductor because electrons move freely and at high speed across its surface. This allows it to dissipate heat and withstand intense electric currents without heating up.

Graphene has a large surface area (2630 m²/g), providing it with self-cooling capabilities and extensive interaction sites.

The hardness of graphene is superior to that of diamond and approximately 200 times stronger than steel at equal thickness.

It is also rigid, capable of withstanding significant stress without deforming.

Graphene is a biocompatible material with excellent antimicrobial capacity.

It is very dense and impermeable, even to the penetration of the smallest molecules, such as helium.

What challenges does the cement industry face?

Globally, several developments and initiatives are underway to improve concrete properties and reduce its environmental impact.

These efforts converge on key objectives such as reducing carbon footprint, energy consumption, decreasing water usage, and promoting material recycling.
