Effect of Steel Fibre and Plastering Sand on GGBS and Silica Fume Based Geo-Polymer Concrete

Due to environmental hazards including ozone layer depletion and difficulties with global warming, the globe is moving towards eco-friendly building materials. Since geopolymer is employed in this study as a new binder instead of regular Portland cement (OPC), the concrete produced must be both long-lasting and environmentally benign. It makes use of by-products from several industries, including silica fume and Ground Granulated Blast furnace Slag (GGBS). This approach produces a sustainable building material while also significantly reducing CO2 emissions. As the primary components of the geopolymer in this study, GGBS and alkaline liquid (a mixture of sodium hydroxide and sodium silicate) were utilised. It is calculated that the sodium silicate to sodium hydroxide solution mix design ratio is 2.5:1. Cast samples of M60 geopolymer concrete with steel fibre and M60 geopolymer concrete with plastering sand are tested for compressive strength and split tensile strength. They underwent a room-temperature ambient cure. This finding indicates that plastering sand combined with fly ash greatly increases the strength of geopolymers, making them an environmentally benign and potential replacement for cement concrete.
