Integrating Nanostructure 2D graphene-silver and Cobalt oxide for Improved Mechanical Strength and chemical properties

This study explores the synergistic effects of reduced graphene oxide (RGO) doped with silver nanoparticles (AgNPs) and nanostructured cobalt oxide (Co₃O₄) on enhancing the mechanical and structural properties. The exceptional tensile strength, high surface area, and flexibility of RGO, combined with cobalt oxide's thermal stability, chemical resistance, and catalytic properties, create a robust composite structure within the cement matrix. Through a comprehensive experimental approach, including advanced material characterizations, mechanical and electrochemical analysis, the results demonstrate significant improvements in the mechanical compressive strength and enhanced resistance to freeze-thaw cycles and chemical attack. Adding 1 wt% RGO.Ag/Co₃O₄ increased compressive strength by about 300%. The resulting composite exhibits self-sensing capabilities for real-time structural health monitoring, offering a transformative approach to sustainable infrastructure development. These findings pave the way for next-generation cementation materials with superior mechanical performance, reduced maintenance needs, and lower carbon footprints, addressing critical challenges in modern construction, environmental sustainability, and different applications.
