Abstract: With the increase in demand for the performance of the material, it is essential to have binder which is reasonably priced, environmental friendly and allow better process efficiency. With respect to the same, Sodium silicate based formulations have been used for increased efficiency. The paper presents the work carried out for the improvement of mechanical properties of fly ash by adding a binder sodium silicate. Sodium silicate is added as a binder with cement and fly ash and then compacted. .The compacts were treated in normal water at room temperature for 3 days, 7days and 28 days. The compressive strength, flexure strength were investigated. Sodium Silicate as surface treatment is also investigated by keeping at compacts in room temperature and curing is done under special condition. Lastly beneficial for protecting from chloride attack is also investigated. It was observed that compressive strength of fly ash increased with curing of sodium silicate and particles were dispersed and deviated from their globular equi axed shaped to multifaceted type
