Due to clay having little or no impressive engineering properties causes a need to develop its properties prior to construction taking place as foundation play a very essential and important role hence the need for soil stabilization techniques. This study focuses on the utilization of waste glass in stabilizing and improving the soil shear strength parameters. Waste glass passing 0.075 µm sieve and 0.300 µm sieve was sequentially added in soil with 0, 6, 8, 10 and 12%. According to unified soil classification system the soil is low plasticity clay, CL. Direct shear strength tests were performed on un-stabilized soil and waste glass added sample to see the effect of waste glass addition on cohesion and angle of internal friction. From the results obtained 10% was found to be optimum addition value for waste glass for this since it improves cohesion values from 4 to 12 kPa for 0.300 µm sieve passing added waste glass and 4–17 kPa for 0.075 µm sieve passing added waste glass while angle of internal friction showed a continual decrease for each waste glass added which may be attributed to the characteristics of the waste glass and chemical compositions. Results showed 8% to be the optimum value as internal angle of friction and cohesion values peaked but showed decrease as the percent increased afterwards. Waste glass increases the cohesion amongst the soil particles thereby changing the shear strength parameter for the soil. Waste glass is a suitable stabilizer for clay soil.
