This paper presents the flyash Stabilization is usually based on reactions between flyash and chemical agents. In the present study, a laboratory testing program was done to investigate the strength properties of flyash with lime, PPC and Sodium silicate. Individual geotechnical properties of flyash were determined and then flyash was mixed with different proportions of lime (2-15%), Portland pozzolana cement (2-15%) and sodium silicate (1-5%). These mixes were tested to obtain optimum percentage of lime and sodium silicate. The variation of strength characteristics were also studied by conducting the tests like Unconfined Compressive Strength (UCS), Split Tensile Strength and California Bearing Ratio (CBR) for different curing periods 1, 3, 7 and 28 days for UCS and Split Tensile Strength and 3, 7 & 28 days for CBR. The results are complied in a graphical form to observe the trends for various parameters. The results show remarkable improvement in strength characteristics at compacted condition.
