University of Virginia's (UVA)have developed a groundbreaking 3D-printed cementitious composite that combines graphene with limestone and calcined clay cement (LC2). This innovative material significantly reduces carbon emissions while enhancing strength and durability, making it a sustainable option for modern construction. 

The research team, led by Professor Osman Ozbulut, achieved a 23% increase in mechanical strength through comprehensive studies and a Life Cycle Assessment showed a 31% reduction in greenhouse gas emissions compared to traditional concrete. 

Collaborating with the Virginia Transportation Research Council, the team explored practical applications in transportation infrastructure, emphasising the material's environmental benefits.
