ENGINEERED HYBRID FIBRE REINFORCED TERNARY BLEND GEOPOLYMER CONCRETE COMPOSITE
This invention related to development of novel sustainable geopolymer concrete composite with hybrid fibers incorporating fly ash, ground granulated blast furnace slag and metakaolin as a replacement of cement. The standard tests were conducted on ternary blend geopolymer concrete with steel fibers, polypropylene fibers and a combination of steel and polypropylene fibers in hybrid form. The specimens were tested for compressive strength, splitting tensile strength, flexural strength and modulus of elasticity. The grade of concrete considered was M55. The variables studied were the volume fraction of fibres, viz. steel fibres (0%, 0.5% and 1%) and polypropylene fibres (0%, 0.1%, 0.15%, 0.2% and 0.25%). The process helps in the elimination of cement in concrete and also makes an effective solution for the disposal of industrial by-products like fly ash, ground granulated blast furnace slag and metakaolin. Therefore, this invention is environmental and user friendly as well as it converts the waste into the best in its manufacturing. The addition of fibers in a hybrid form enhances the mechanical properties of ternary blend geopolymer concrete. The increase in the compressive strength was found to be nominal, and a significant improvement was observed in the case of splitting tensile strength, flexural strength and modulus of elasticity. Hence, this composite appears to be a useful for sustainability and also in the case of structures which requires high strength and ductility.
