The substantial challenge on behalf of engineers specifically civil engineers are the scraping of industrial waste output and their storage. To protect environment from the dangerous effect the scraps material should be uses again and again. The only industrial scrap is Fly Ash which is produced throughout the country in every year. Fly ash is a dusty powder acquired from burning of coal through the production of electricity. Dumping of Fly ash is a big issue, to minimize the dumping of Fly ash into big area presently, an experimental survey was carried out to find out the strengthening properties of Fly ash with lime and Sodium silicate. Particularly some parameters like grain size distribution, liquid limit, OMC, MDD, Specific gravity and angle of internal friction of Fly ash were find out and then Fly ash was mixed with various percentages of lime (0-15%) and sodium silicate (1-4%). All the different proportions were tested to acquire optimum percentage of lime and sodium silicate. The difference in shear parameters like cohesion and angle of shearing resistance were practiced by conducting direct shear test. All the tests were completed afterwards a time period of 3hours from starting to the completion of preparation of sample. Every test is performed under the normal stresses of 0.5kg/cm2, 1kg/cm2, 1.5kg/cm2, 2kg/cm2 and 2.5 kg/cm2. The results are collected in a graphical manner to observe the trends for shear parameters. The conclusions show remarkable enhancement in strength characteristics for greater percentages of lime and sodium silicate.
