Evaluation of Glass Powder's Impact on the Atterberg Limits of Anbar Soil

Soil stabilization is crucial for the construction industry in regions with clayey expanding soil. Adding certain materials can enhance the geotechnical properties of the soil. Ground glass powder is studied herein as an additive to clay soil, by applying the Atterberg Limit Test (ALT). The use of ALT can give a basic assessment of the suitability of the soil, which also determines the optimal ratio of the glass material that must be added to the mixture. Laboratory experiments were conducted utilizing the Casagrande apparatus by adding 4%, 5%, and 6% of ground glass to clay soil, and the impact of these percentages on soil characteristics was evaluated. The results exhibited a noticeable change in the mixture limits and plasticity. Increasing the percentage of added glass leads to a decrease in all three Atterberg limits improving soil stability and reducing soil plasticity.
