Strength and Durability Behaviour of Geopolymer-Stabilized Soil
Geopolymer is an inorganic polymer formed by alkaline activation of fly ash. Inertness in excess can neither be digested by nature nor stop itself from being hazardous, and fly ash is one such inert material whose count in the environment is increasing exponentially each day. In the present study, fly ash from Kakatiya Thermal Power Station is deployed in the form of geopolymer for boosting the strength of locally available weak soil. The quantity of polymerization is a function of alkali/ash ratio, sodium silicate to sodium hydroxide ratio and percentage of fly ash. The strength of the soil by the fluctuation of those parameters was studied. The strength and durability of geopolymer-stabilized soil with escalating fly ash percentage are compared with virgin soil sample by using unconfined compression strength test and wetting/drying test. The maximum strength of soil is achieved at 0.6-alkali/ash ratio, an optimum fly ash percentage 30% and liquid ratio 1. In addition, soil survived for 12 cycles of durability test.
