Abstract :
In civil engineering construction, soil is essential, and inadequate soil characteristics can result in serious
structural problems. The extremely expansive black cotton soil, which is primarily found in South India, presents significant
difficulties since it shrinks in dry conditions and swells during the rainy season. Pavements, buildings, and foundations
sustain significant damage as a result of these volume fluctuations. Stabilization methods are necessary to improve the black
cotton soil's engineering qualities. This study investigates the use of fly ash and plastic strips to stabilize black cotton soil.
Fly ash, an industrial by-product from thermal power plants, is incorporated at varying percentages of 5%, 10%, 15%, and
20% to determine the optimal dosage for improving soil strength. Once the optimal fly ash percentage is identified, plastic
strips of 20mm × 20mm dimensions are added at 0.25%, 0.5%, 0.75%, and 1% by weight of the soil. The inclusion of plastic
waste addresses its disposal challenges while enhancing soil properties. The stabilization process aims to improve soil
strength, reduce its expansive nature, and mitigate infrastructure damage Fly ash and plastic strips work together to
improve black cotton soil in an economical and environmentally responsible way, encouraging sustainability in building.
This research contributes to more robust and long-lasting infrastructure by shedding light on the possible use of industrial
waste for soil stabilization.
