Graphene in Building Materials
In building materials, graphene can be used as a performance additive and an effective aid in the decarbonization pathway. Graphene’s incorporation into cement, concrete, and asphalt significantly enhances their mechanical properties. Graphene can increase tensile strength, compressive strength, and overall durability even at low concentrations. This improvement is particularly crucial for infrastructure projects, where the longevity and resilience of materials directly impact maintenance costs and lifecycle sustainability.
Graphene’s impermeability to gases and liquids can be used to enhance the waterproofing and corrosion resistance of building materials. In coastal or industrial environments where structures are exposed to harsh conditions, graphene additives can provide an additional protective layer, mitigating the effects of moisture and aggressive chemicals. Graphene’s strength-to-weight ratio allows for the development of lighter materials that do not compromise on strength. This is particularly beneficial in reducing the overall weight of structures, leading to lower transportation and handling costs, and enabling the design of more innovative architectural solutions.
As the construction industry is one of the largest contributors to global carbon emissions, the integration of graphene into building materials presents a significant opportunity to reduce the carbon footprint of construction projects. The strength-enhancing properties of graphene allow for the reduction of the amount of material required to achieve desired performance levels. For example, graphene-enhanced concrete can achieve the same or better strength with less cement, the production of which is a major source of CO2 emissions.
This reduction in cement usage directly contributes to lower emissions. The durability and extended lifespan of graphene-enhanced materials contribute to sustainability by reducing the need for frequent repairs or replacements, thereby minimizing the environmental impact associated with material production, transportation, and construction processes. The longevity of these materials ensures that resources are used more efficiently, and waste generation is minimized.
