ASSESSMENT OF STRENGTH BEHAVIOUR OF COHESIONLESS SOIL EMBEDDED WITH WASTE FIBRE MATERIALS

The usefulness of randamonly dispersed waste fibres is shown in this article via a series of experiments conducted on cohesion-free soil with coir fiber. Soil reinforcement is a method of treating soil in order to enhance its performance. The Strengthening By using waste fibers such as coir fiber, which is environmentally benign, soil may be improved. Using the above-mentioned materials, rather than synthetic fibers, is the most appropriate, cost-effective, and environmentally responsible option. Instead of manufactured fibers, researchers can readily purchase natural or waste fibers. Natural fibres' biochemical characteristics aid in producing the optimum soil reinforcement and increasing soil shear strength. The swelling capacity, plastic limit, liquid limit, plasticity index, shear strength, cohesion, and compaction properties of the cohesion-less soil are all evaluated. Reinforcement techniques are used on soils with low stability. Various coir fibre percentages (0, 0.5, 1.0, 1.5). The tests were carried out with the sample on four proportions of 0, 0.5, 1.0, and 1.5. However, each of these combinations is carried out at a distinct soil density and moisture content ratio. Direct shear test, conventional proctor test, and unconfined compressive test were used in this investigation. As a result, data such as stress/ displacement and stress/ strain graph may be compared. We can calculate the C-value of reinforced soil using the results of this experiment. Slope protection, building foundations, and pavement layers are all built using this material.
