Concrete and Cement
Adding graphene to concrete and cement increases their strength and durability while substantially reducing CO2 emissions by 40% to 50%. Additionally, this enhancement allows for a significant reduction of total material usage by 30% to 50%.
Concrete is the second-most consumed product on Earth. It is a versatile and widely used material composed of cement, aggregates (such as sand and gravel) and water and other additives and mixtures.
$550 BILLION MARKET SIZE
Cement-based concrete represents the most heavily used material in the construction industry due to its affordability and high compression strength.
Over 2 billion tons of concrete are consumed every year and that amount is expected to grow at 8% per year, driven by infrastructure demand fueled by growing populations and replacing older structures.
Features and Benefits of Concrete and Cement with Graphene
Tests have shown that graphene improves cement flexural strength by 41% to 51% and compressive strength by 27%.
Graphene usage results in a 30% to 50% reduction of total concrete material required for the same projects, and reduces emissions of CO2 by 446kg per tonne of concrete produced.
Graphene provides a protective coating to concrete, keeping water and other corrosive gases and liquids from damaging the rebar used in construction, thus extending its life and reducing maintenance costs.
Graphene reduces concrete’s water permeability, virtually eliminating exposure to freezing/thawing damage.
Graphene has the potential to reduce CO2 emissions by 40% to 50%. Every 1,500 tons of concrete with graphene used reduces the equivalent amount of CO2 as taking 100 cars off the road.
