Abstract
Peat soil is one of the problematic soils known for being extremely soft and weak. However, ground improvement techniques can be opted to improve the strength of peat soil. There are various methods of ground improvement technique including chemical stabilization method. Since peat has a high organic and fiber content and acidic, it is difficult to achieve the expected strength after chemical stabilization. Due to that, the aim of this study is to improve the compressive strength of amorphous peat through pretreatment and by using the most efficient chemical stabilizers. In this study, peat samples were collected from Kpg Meranek, Kota Samarahan and mixed at its natural moisture content with cement and fly ash plus lime at water to additive ratio of 3.0 and 3.5. The compressive strength of the samples was obtained by unconfined compressive strength (UCS) test. The results of the study have shown that the unconfined compressive strength values obtained after 28 days and 60 days curing period are insignificant. The peat samples that are pretreated and chemically stabilized using cement at 3.0 water to additive ratio recorded the highest value with UCS value of 16.042 kPa after 60 days of curing. The values obtained are very low compared to published data from other studies. However, the pretreated chemically stabilized peat samples have shown strength development compared to original peat samples without pretreatment and chemical stabilizers.
