Abstract: Geopolymers are one type of aluminosilicate materials formed through the polymerization of silicate and aluminate tetrahedrons. Geopolymer is used as a non-calcium-based stabilizer to mix with sulfate-rich soils. The stabilized soils were exposed to deionized water for 7 days until the volume of soil samples reached constant. Volumetric expansion of the sulfate-rich soil samples stabilized with metakaolin based geopolymer was 7 times lower than those stabilized with lime while the mechanical strength of stabilized soil samples were significantly improved.
