Comparative Effects of Lime and Banana Leaf Ash on Engineering Property of Soil

This study compared the effects of lime and banana leaf ash BLA on engineering property of selected soils. This was with a view to identifying the more effective stabiliser. To achieve the aim of the study, soil samples were collected from two identified locations in Ile Ife. Using standard procedures, the soils were subjected to preliminary and geotechnical tests such as natural moisture content, particle size analysis, specific gravity, Atterberg limit, compaction and California bearing ratio CBR . Thereafter, the soil samples were separately treated with lime and BLA at 2 , 4 and 6 by weight of dry soils. The stabilized soils were then subjected to CBR tests. Results of preliminary and index property tests showed that the tested soil samples belong to A 2 7 category, according to American Association of State Highway and Transport Officials AASHTO classification system. The CBR values of natural soils indicate that the soils were good subgrade and subbase materials. For both samples, the CBR values increased with increase in lime content and BLA. However, optimum maximum value of CBR was obtained at BLA content. The highest percentage increase in CBR was obtained at the optimum content 4 of BLA. The study concluded that BLA at 4 content resulted in a more significant improvement in the engineering property of tested soils than lime. E. O. Ayoola | G. O. Adunoye | H. I.
