Researchers at the University of Virginia have made significant progress in the field of 3D printed concrete. They have developed a more sustainable printable cement-based composite material. This new material combines graphene with limestone calcined clay cement (LC2), which not only improves strength and durability, but also significantly reduces carbon emissions, providing a new solution to environmental challenges in 3D printed buildings. The research findings were published in the latest issue of the Journal of Construction Engineering.

Researchers explored the flowability, mechanical properties, and environmental impact of this material, and the results showed that compared to traditional printable concrete mixtures, this graphene reinforced LC2 concrete can reduce greenhouse gas emissions by about 31%.

Researchers say that this innovation is crucial for the future of the construction industry. Compared with traditional high carbon emission 3D printing methods, the new 3D printed concrete exhibits better mechanical properties and lower environmental impact, achieving a win-win situation.
