This research presents the stabilization of Mukah Peat using Fly Ash (FA) , Pond Ash(PA) from a coal fired thermal power station and Rumbia Ash (RA) disposal from the Sago factory. Peat or highly organic soils are well known for its high compressibility, high natural moisture content, low shear strength and long-term settlement. This study investigates the effect of different amount (i.e, 5%, 10%, 15% and 20%) of FA, PA and RA Ash content on peat, collected from Mukah-Dalat Road, Sarawak Malaysia. The effects are investigated focussed on compaction and unconfined compressive strength (UCS) properties. The UCS value of peat increases significantly with the increase of stabilizer and curing periods. Based on the EDX analysis, the chemical component of FA stabilized with Mukah Peat consists of Silicon (Si) at 16% in 15% and 20% admixtures. While chemical content of RA stabilized Mukah peat consists of 14% Si in 20% admixtures. The addition of 20% PA in Mukah peat contributes to 9% Si content. Thus, it is observed that the content of Si in any mix influences the strength of stabilized peat. Hence, the chemical results for Mukah stabilized peat could be correlated with the UCS values.
