Abstract
Peat is a problematic soil and it is common problem that faced by engineers in construction. The characteristic that has been noted before which is, high moisture content, poor shear strength, great compressibility and long-term settlement. There are several past studies that showing peat soil treated using blended cement or Eco Processed Pozzolan (EPP). Normally, they will mix EPP with some chemical substance or waste material like fly ash, shredded waste tire chips, Calcium Oxide (CaO), Natrium Hydroxide (NaOH) and many others. For this research study, it focusses on stabilizing peat soil using EPP and CaO. There are three main testing that conducted in this research study, which are, Index Properties Testing and Compaction Test. For Index Properties testing, there were five (5) experiment conducted to study the index properties of disturbed peat soil which are, moisture content, fiber content, liquid limit, organic content, pH and specific gravity. Next, for the Compaction Test, using 2.5kg rammer to define optimum mixture of stabilizer that mixed with different volume, 5%, 10%, 15% and 20% of stabilizer. In this study, the expected result is to inspire and in-depth study the use of EPP material and chemical Cao as for peat soil stabilizer for better utilization problematic soil. The main finding was the mixture with the exact amount of moisture, EPP and Cao help stabilizing the soil and cured peat soil. Thus, this study confirms the idea to treat peat with EPP and Cao, enhancing the properties of peat soil and sustain the settlement over loading for period of time accordingly. 20% mixed of EPP and CaO produce the highest dry density, showing that dry density increases linearly with the amount of mixture to stabilize peat.
