ABSTRACT
Sabkha soil is one of the most problematic and hazardous soils in arid areas. Due to the geotechnical concerns connected with sabkha soil an appropriate treatment method must be implemented before using it as a construction material. Ordinary Portland cement (OPC) is one of the major chemical additives utilized to minimize the geotechnical issues of sabkha soil. However, OPC manufacturing is a significant source of carbon dioxide (CO2) emissions globally. Consequently, environmental issues are gaining prominence around the world, prompting the immediate need for new sustainable solutions. Hence, this paper aims to investigate the potential of alkali-activated material as a promising alternative to OPC. The results show that the geopolymer treatment significantly increase the UCS compared to untreated sabkha soil, and the highest value is obtained when using the molarity of NaOH of 8 M.
