Observation of the Behavior of Organic Soil by Adding Lime, Fly Ash and Cement

Organic soil is a kind of soil that contains organic matter. Soil organic matter (SOM) is that kind of organic matter of soil, which consists of different ingredients such as plants, animal residues, cells and tissues of soil etc. at various stages of decomposition. Normally organic soils are rich in water content with high porosity and therefore successful stabilization has to depend on the type and amount of binder added. The commonly used binders are lime, fly ash and cement. This study reveals the variation of behavior of organic soil-lime, organic soil- fly ash and organic soil-cement mixtures at an amount of 5%, 10%, 15% and 20 %. The maximum shear stress and maximum angle of friction were found for 10% cement mixed with soil
