Concrete is the second most consumed product on earth, after water. The world consumes around 20 billion metric tonnes of concrete each year. Although cementitious materials are widely used, they tend to have poor mechanical properties and suffer from high permeability to water and other damaging chemicals which cause low durability. Production of cement used in concrete materials is also one of the largest contributors to CO2
emissions (5-6% of global man-made CO2 emission annually).
Turbostratic graphene offers the potential to cost effectively increase compression strength and tensile strength, thus reducing cement consumption and lowering emissions contributions. Initial testing with the addition of up to 0.06 wt% of turbostratic graphene added to concrete has demonstrated a >30% improvement in these key properties, and thus could allow the volume of concrete to be reduced by up to 30% while maintaining equivalent structural integrity
