Experimental Study on Banana Fibre-Reinforcement of a Soil Stabilization with Phosphogypsum

The soils with poor bearing capacity and shear strength need to be stabilized to make them suitable for construction. In this study, banana fiber (obtained from pseudostem) was used as a natural fiber to stabilize the soil. Stabilization with natural fibers is a cost-effective and environmentally friendly way to improve the soil. Chemical or synthetic fibers harm our environment; using natural fibers is a way to achieve balance. This study presents the effect of banana fiber on the soil and compares the engineering performance before and after stabilization. In this study, the effect of banana fiber on soil strength was evaluated by conducting direct and uncompressed compression tests on two different soil samples. The impact samples were collected from two different construction sites. In the laboratory. Proctor compression tests were conducted on various percentages of coconut fiber. Also, direct tests and compression tests were conducted on different parts of banana fibers at moisture content (OMC). The results of experiments with and without banana fiber reinforcement were compared to obtain the best amount of fiber reinforcement (% of soil sample) required to stabilize weak soil and estimate the effect of bearing capacity.
