American engineers from the University of Virginia have created a cement composition with the addition of graphene that reduces greenhouse gas emissions. The research was published in the scientific journal broadcasting Journal of Civil Engineering (JOBE).
According to the authors of the development, the new material combines graphene with limestone and calcined clay cement, increasing strength and durability. The finished composite can be used in 3D printers to construct buildings using the additive (printed) method.
A study on the properties of the composition showed that graphene-reinforced concrete can reduce greenhouse gas emissions by 31% compared to traditional additive construction mortars.
One of the study’s authors, a postdoctoral researcher in the Department of Building and Construction, noted: “Concrete not only exhibits better mechanical properties, but also has a lower environmental impact, making 3D concrete construction technology superior to traditional 3D printing methods with higher carbon emissions.” It makes it more sustainable.” Environmental Engineering at Zhangfan Jiang University of Virginia.
Previous scientists developed Ultra-strong concrete based on the structure of human bones.
