Geopolymer treatment has proven to be a more efficient method of stabilizing municipal solid waste (MSW) ash, compared to cement stabilization, offering the additional benefit of reducing the material's carbon footprint. It is observed from the result that the MSW ash is a lightweight material with a specific gravity of 2.26. The compaction behavior of untreated MSW ash is determined to obtain maximum dry density (MDD) and optimum moisture content (OMC). The unconfined compressive strength (UCS) of the treated sample were determined at different parameters to achieve an optimum mix. The percentage Improvement factor ((If (UCS)) is calculated with the respect of UCS value of untreated MSW ash. It is observed from the calculation of If (UCS) for 7 days curing of 50 ℃ curing temperature and 60 ℃ curing temperature is 360%, and 700% respectively. Also, the test results indicate that the molar concentration of sodium hydroxide, days of curing, temperature of curing, and ratio of sodium hydroxide (S–H) to sodium silicate (S–S) significantly affect the strength.
