Abstract
Rapid development in Malaysia has encroached to the area which are considered as problematic ground like peat land. However, strength characteristics of natural peat soil need some improvement with the introduction of economical, efficient and sustainable methods. The used of byproduct material in stabilizing of peat soil become more reliable and expanded. In this paper, the physical properties of the peat soil were classified and identified accordingly. Peat treated with pond ash (PA) and hydrated lime (HL) in seventeen (17) different types of mixtures were prepared. Each mixture was prepared using PVC molds with a diameter of 50 mm and a height of 100 mm and then soaked in water for ten (10) different soaking period. The strengths of Unconfined Compressive Strength (UCS) were comparatively investigated. The results have shown that the peat becomes stronger when the percentage of PA-HL and soaking period increased. Of the investigation, the results show the strength characteristics of peat treated with PA-HL against soaking time. Peat with a mixture of 15 and 20 % of PA in various compositions of HL and soaking period exceeding 60 days have presented a great unconfined compressive strength. These findings indicate that the PA and HL is potentially as a stabilizer for peat soil, which experience a high water table.
