The Effect of Lime on Organic Soils Stabilization

- Organic soils or soils with an organic content have been used with varying content of organic matter as concepts with different meanings in geotechnical engineering. These soils are decomposed non-living organic matter such as plant and animal remains, and this decomposition process is mainly influenced by bacterial activity, hot weather, good humidity and oxygen accessibility. In this study, lime was added in soils with organic content to examine their effects on soil shear strength. Different percentages of sand, clay, and peat have been used in this study. In this study, different percentages of lime (4%, 6%) have been used for soil stabilization. The curing times for this study are 3 days, 7 days, 28 days. Finally, after performing the necessary tests on soil shear strength and comparing the effects of lime in soils with organic content, little effect of lime on increasing the strength of soils with organic matter was observed.
