Rapid development in Malaysia has led to urban development encroaching into the peat land area. Nevertheless, the physical properties of peat which is regarded as a problematic ground has prompted many studies on various methods of stabilization. The used of byproduct material then become a need for a sustainable environment. This paper presents the results of the unconfined compressive test of stabilized peat by admixture method. A constant composition of pond ash as byproduct material (10%) and three different contents of hydrated lime (2%, 4% and 8%) were mixed together with peat respectively. The samples were prepared in the mould and allowed for curing under 0, 14 and 28 days before the test. The experimental results demonstrated that the compressive strength and stiffness of the stabilized peat increases with the hydrated lime content and also with curing time. It indicates that the mixed of pond ash and hydrated lime can promote a better compressive strength of peat, hence become a potential admixture for stabilizing the peat.

Thermo Physical Properties

In the present study effect of different plasters like cement plaster, mud, cow dung and coatings like paint, hydrated lime, charcoal on the thermo – physical properties such as thermal conductivity, overall thermal transmittance, resistance of Light Weight Blocks (LWB) using pond ash has been evaluated. Result of the study state that, cow dung is the best amongst all other plasters used. Cow dung increases thermal resistance of Light Weight Block (LWB) from 0.391 to 0.505 m2K/W. Thermal resistance increased by using other plasters lies between 0.391 to 0.505 m2K/W. The study of curing of LWB from 56 days to 90 days has been made and it is found that thermal conductivity is reduced by 5% and thermal resistance is increased by 3% comparing the duration of curing from 56 to 90 days. Further, effect of activator on the compressive strength & demolding time has also been studied. When activator is used, there is an increase in compressive strength at 56 & 90 days at all levels of replacement when compared to without activator. Reduction in demolding time from 48 hrs. varies between 6 – 12 hrs.

Strength Capacity

Construction activities on peat soils are found to be extremely difficult as the soil is profound as soft soil and has low shear strength and high moisture content. Due to alternating swelling and shrinkage nature, it causes serious damage to the structure above it. This happens due to repetition of drying and wetting of soil. Stabilization of soil is commonly applied to improve the mechanical properties of soil prior to soil engineering works. This soil improvement method is advantageous and effective one by using waste materials. Waste in our country is divided in various types and it includes domestic wastes, industrial wasters, agricultural wastes etc. Because of difficulties to diminish these wastes without affect to environment and surroundings, it can be used as a stabilizing agent in the soil. Therefore, this experimental study carried out to evaluate the effect of Rice Husk Ash (RHA) and sawdust on engineering properties of the peat soil. The properties such as compaction and unconfined compressive strength are determined separately with sawdust and added of RHA in peat soil at a variety of percentages (2.5%, 5% etc.) in addition small amount of constant rate of lime with 2% of the dry soil weight. By obtaining the results, it can deduce a promising and improving result in stabilizing the soil with sawdust and Rice Husk Ash in both economic and strength capacity. This will not only solve the waste disposal problem but also enhance the strength characteristics of soil significantly.
