Abstract

Peat soil commonly occurs as extremely soft, wet, unconsolidated deposits commonly found at surface that are integral parts of the wetland systems. This problematic soil is known for their high compressibility and low shear strength. The study of index properties includes determination of natural moisture content, particle size distribution, Atterberg limits and loss of ignition. Chemical test also included in this study which is pH test. Cement is the most widely used additive for soil stabilization due to its high strength and the addition of lime for these soils had give potential in increasing strength of this soils. Hence, a study on the improve soil properties is seems very important to gain on insight of the efficiency of stabilization process. Soil samples utilized in this property was taken from Rengit, Batu Pahat, Johor. The aims of this research are to obtain the index properties of peaty soil that stabilized with cement and lime and the optimum percentage of additives materials needed in this soil. The constant value of 11% lime was used while cement percentages were 5%, 10%, 15% and 20% from dry weight of soil. Testing was made before and after the soil was cured for 1, 3 and 7 days. Comparisons results achieve between before and after stabilization were discussed in this paper summary. The results show that liquid limit and shrinkage limit percentages decreased while pH and specific gravity value increased when additives percentages increasing. From the study, it shows that the optimum percentage of cement that need for the stabilization in this peaty soil is 20% after 7 days curing.
