Abstract
Naturally found soil may or may not be strong enough to hold superstructures. For weak soil
the method of soil stabilization is used to increase its strength. Consequently, randomly
distributed fibre-reinforced soils have recently attracted increasing attention in geotechnical
engineering. Among various methods of soil stabilization, one is to reinforce the soil with
fibres. This study investigates and compares the differences between unreinforced and
reinforced soil. Soil here is reinforced with polypropylene fibre of length 24mm with varying
percentage by mass of soil as 0.6% 0.8% 1.0% and 1.2%. The soil was tested and basic
properties were identified. Unconfined compression tests have been carried out to draw
inferences about the effect of polypropelene fibres on strength of soil. This study also finds
out the optimum dosage of polypropylene fibre by analysing the results and obtaining the best
values possible.
