Geopolymer is a type of cementitious substance that can replace traditional Portland cement in certain geotechnical engineering uses, such as soil stabilization. It offers the benefits of significantly reduced hazardous emissions and energy consumption. To produce geopolymers, two essential conditions must be fulfilled: the presence of source material abundant in Silicon (Si) and Aluminium (Al), and the addition of an alkali activator, such as sodium/potassium hydroxide. Sodium hydroxide (NaOH) is commonly employed in geopolymer manufacture as a substitute for potassium hydroxide (KOH), together with a silicate solution, to enhance the dissolution process. The utilization of contemporary technologies to enhance the soil's ability to withstand external forces has led to the stabilization of diverse soil compositions.This study investigates the use of specific geopolymers as additives or stabilising agents to improve the soil's resistance properties, as analysed by geotechnical specialists. Studies have demonstrated that the incorporation of geopolymer materials, such as fly ash and slag, enhances many soil properties, including compaction, permeability, and resistance to deformation.
