Municipal solid waste management is a global concern due to the growth rate of population and urbanization. This paper aims to determine the possibility of utilization of municipal solid wastes such as fired clay brick powder (FCBP), eggshell powder (ESP), and recycled glass powder (RGP) for the stabilization of aeolian sand. Using such green binders can eliminate the perils associated with inappropriate waste disposal. Different combinations of FCBP, ESP, and RGP were added to the soil, and two activators (KOH and NaOH) were used to study the effects on its engineering and chemical properties. The effects of various parameters were investigated based on unconfined compression strength tests (UCS), pH tests, and scanning electron microscopy (SEM) tests. The results revealed that using all of these three precursors leads to the co-existence of calcium silicate hydrate (C-S-H) gel with the geopolymeric gel (N-A-S-H) and provides the highest UCS value. According to the obtained results, NaOH had a better ability to dissolve the precursors’ particles than KOH, resulting in better polymerization. The optimum composites found in the research had a 91-day UCS of 5.32 MPa, which are suitable for the base material in pavement construction.
