Waste Glass Powder - Opis:
- The weak soil is largely distributed worldwide and creates problems in constructing pavements, roadways, structures, irrigation systems and foundation works due to low shear strength and bearing capacity. The ways of improving soil is known as soil stabilization. Various soil stabilization techniques are using but none of them are cost effective and environmentally friendly way. The present study aims to effect of soil stabilization with waste glass powder which will reduce the cost and is environmentally friendly. To investigate the effect of glass powder in cohesive soil different types of index and geotechnical engineering tests are conducted and compared with the virgin soil. Glass powder was mixed with the soil samples by 2%, 4%, 6%, 8% and 10% of dry weight of soil to conduct the tests and to determine the optimum percentage of glass powder. The Liquid Limit (LL), Plastic Limit (PL) and Plasticity Index (PI) continuously decreased and found 33.9%, 18.4% and 15.5% respectively at 10% of glass powder. Maximum dry density (MDD) was increasing and found constant and Optimum Moisture Content (OMC) was decreasing when added glass powder. The both Unsoaked and Soaked California Bearing Ratio (CBR) was increasing with the addition of glass powder and found maximum value 22.5% and 10.4% respectively. Unconfined compressive strength (UCS) was increasing up to 8% of glass powder and found to 133.5 KN/m2 and then decreased to 119.7 KN/m2 when added 10% of glass powder. Shear strength parameter also increases with the increase of glass powder. The study found that the optimum percentage of glass powder is 8% of dry weight of soil.
