Abstract: ABSTRACT The present invention relates to a sustainable high performance hybrid geopolymer concrete using fly ash as aluminosilicate precursor and ground granulated blast furnace slag (GGBS) as aluminosilicate precursor, activated with an alkaline solution comprising sodium hydroxide and sodium silicate with a molarity of 12M. Moringa oleifera fibre (MOF) is used as a macro-scale reinforcement while graphene oxide (GO) is used as a nano-scale reinforcement simultaneously during the reinforcement of the geopolymer matrix. The Moringa oleifera fibres contribute to crack bridging and enhance tensile and flexural properties, whereas graphene oxide helps to densify the matrix, refine the pores, bond with the matrix, and control microcracks. Experimental study with ambient curing showed that the optimized composition of hybrid material was 0.5% MOF and 0.005% GO. The developed composite achieved approximately 58 MPa compressive strength, 6.32 MPa splitting tensile strength and 6.77 MPa flexural strength. Microstructural analysis by FE-SEM, EDX, XRD and FTIR supported the improved particle packing, microcracking reduced, and strong bonding between the fibre and matrix materials as well as the particle and matrix materials; formation of geopolymeric N-A-S-H and C-A-S-H gel phases. In view thereof, it is the object of the invention to provide a multi-functional, fibre–nano reinforced geopolymer composite having improved mechanical strength, crack resistance, matrix compactness and structural integrity for sustainable applications in high performance construction.
