“…In general, peat soil composed of fibrous organic matters that are organic residues of plants formed through incomplete process of decomposition due to the lack of oxygen. According to a recent literature, wet and organic peat soil strength can be effectively improved using dry polymeric binder such as MUF resin for a specific purpose [1,13]. Formaldehyde resin such as powdered MUF (MUF-P) used in this study is widely used in previous studies to strengthen various types of material and soil particulary in the area of rapid application for soil stabilisation method.…”

Peat is commonly described as a soil that is possess to high rate of compressibility due to present of high organic substance derived from plant origins. Peat soil naturally associated with settlement and consolidation characterized by its high initial void ratio, organic content and water holding capacity. This paper presents the performance of peat soil treated with powdered melamine urea formaldehyde resin (MUF-P) in term of compression and consolidation behaviour under standard compressibility test. In this study, series of one-dimensional oedometer test were carried out with the load increment method from 12.5 to 400 kPa after 24 hours of each loading. Peat soils under high moisture condition were mixed with MUF-P within 3 days of stipulated periods of curing times. The results indicate that increasing the MUF-P proportion has improved the compressibility characteristics of peat soil. The result shows the values of compression index (Cc) decreased from 4.12 to 0.9, and secondary compression index (Cα) were also decreased from the range of 0.026 to 0.320 to the range of 0.080 to 0.161 with the increase of peat MUF-P proportions up to maximum 350 kg/m3.
