Abstract

Geopolymer concrete is an innovative and sustainable alternative to conventional Portland cement-based concrete. It is produced by activating industrial by-products such as ground granulated blast furnace slag (GGBS), silica fume, and fly ash with alkaline activators. This study aims to maximize the performance of geopolymer concrete by optimizing the integration of GGBS, silica fume, and fly ash. The research investigates the effects of varying proportions of GGBS, silica fume, and fly ash on the fresh and hardened properties of geopolymer concrete. The experimental program includes the evaluation of workability, compressive strength, flexural strength, and durability characteristics of the geopolymer concrete mixtures. To achieve the objectives, a series of geopolymer concrete mixtures with different combinations of GGBS, silica fume, and fly ash are prepared and tested. The mix design is based on a constant alkaline solution-to-binder ratio to ensure a consistent level of activation. The influence of each supplementary cementitious material (GGBS, silica fume, and fly ash) on the mechanical and durability properties of the geopolymer concrete is thoroughly examined. The experimental results will be analyzed and compared to identify the optimal combination of GGBS, silica fume, and fly ash for enhancing geopolymer concrete performance. The findings will provide valuable insights into the synergistic effects of these materials on the fresh and hardened properties of geopolymer concrete, enabling the development of more sustainable and durable construction materials.
