For the first time in the world, geopolymerized brine sludge has been developed as it leads to the formation of enhanced geopolymeric gel which not only helps in further improving the interfacial binding of the conventional geopolymeric matrix using jute and glass fiber as reinforcement but also helps in making the toxic elements non-leachable from the geopolymerized brine sludge due to enhanced geopolymerization reaction taking place in the brine sludge incorporated advance matrix. The advanced geopolymerized matrix is capable of providing improved interfacial binding due to formation of additional C–S–H gel along with Na–S–H gel of conventional geopolymeric matrix in the geopolymeric brine sludge system. The simultaneous presence of desired components and constituents in the single matrix of geo polymeric brine sludge lead to the enhanced homogeneity among the reinforcement and matrix. The geo polymerized brine sludge was further used for making advance composites (AC) using closed mold fabrication system, with hand layup manual technique (a) without any fiber reinforcement, (b) with jute fiber reinforcement (c) and with glass fiber reinforcement of dimensions 12 in. × 12 in. × 6 in. The morphologies of all the three developed AC were examined using SEM and were also tested for their various mechanical properties like tensile strength, flexural strength, impact strength, abrasion resistance. The results indicate that fiber reinforced based AC shows the increase in the mechanical properties as compare to non-fiber reinforced AC. Further, the glass fiber reinforced AC showed better results than jute fiber reinforced AC. This remarkable enhancement is due to the unique properties of fiber in tolerating greater bending and fracture forces than the non reinforced matrix based materials. Graphical Abstract
