Geopolymer technology represents a significant advancement in concrete production, especially in mitigating the environmental concerns that arise from the use of conventional cement materials that emit significant amounts of CO2. By substituting cement with alternative ingredients such as Fly ash and Ground Granulated Blast Furnace slag (GGBFS), a more environmentally friendly approach is possible. Geopolymer concrete, utilizing a synthetic resin binder that reacts with alkaline solutions like sodium hydroxide and sodium silicate, emerges as a viable alternative. This project aims to enhance the properties of fly ash and slag-based Geopolymer concrete by incorporating composite fibers. It seeks to investigate the effects of Crimped steel, Polypropylene, and Glass fibers on the compressive, split tensile, and flexural strength of Geopolymer concrete. By introducing varying proportions of fibers, ranging from 0.5% to 1.5% of the concrete volume, the study intends to determine their impact on the mechanical properties of concrete. These investigative efforts hold significant potential for broadening the application of Geopolymer concrete, providing an efficient alternative to traditional cement concrete for a wide range of construction applications.
