Assessment to the Solid to Liquid Ratios on the Soil Strength and Water Absorption of the Kedah’s Soil

Abstract:

The purpose of this paper is to assess the solid to liquid ratios on the compressive strength and water absorption of Kedah’s soil by using geopolymerization method. Fly ash and soft soil were mixed with alkaline activators namely sodium hydroxide (NaOH) and sodium silicate (Na₂SiO₃) for preparing stabilize the soil sample. The geopolymerization process for soil stabilization was synthesized by the activation of fly ash and soil with alkaline solution at four different solid to liquid ratios which were 1.5, 2.0, 2.5, and 3.0 at a specific constant ratio of Na₂SiO₃/NaOH solution of 0.5. The compressive strength up to 4.77 MPa was obtained at 3.0 of solid to liquid ratio and the water absorption has become increasingly lower to 2.28% as the ratio of solid to liquid increases in 7 days curing at room temperature.
