Characterization of peat soil treated with polymer resin by unconfined compressive strength test

N.N. Nik Daud1, *, M.N.M. Daud2

HIGHLIGHTS

  • Problematic peat soil was treated with polymer resins (MUF and PF).
  • Unconfined compressive strength (UCS) and moisture content were studied.
  • Mixed samples with PF resin only managed to achieve 36.5 kPa of UCS.
  • Mixed samples with MUF resin had an optimum UCS of 127.5 kPa.
  • MUF resin had a better performance compared to PF in UCS development.

ABSTRACT

In this paper, the problematic peat soil was treated with the (MUF) and Phenol Formaldehyde (PF)/Phenolic resins as reactant polymer using air-curing method. A series of laboratory tests were conducted such as unconfined compressive strength (UCS) and moisture content. The aim of this study was to examine the development of UCS and the changes in moisture content as peat soil samples treated with the liquid forms of polymer, and cured at targeted time periods of 1, 3, 5, 7 and 14 days. The results showed that the UCS of treated soil increased significantly with addition of MUF resin. However, the addition of PF resin did not show any significant increase of the UCS. The treated peat samples with 25% of PF at 14 days of curing period only managed 36.5 kPa of UCS. The peat soil mixed with 35% of MUF resin in liquid form had appeared to have optimum the UCS of 127.5 kPa at moisture content of 182% and the cured period of 14 days. It is revealed that the MUF resin had a better performance compared to PF resin in UCS development.
