Abstract: Glass is a transparent material produced by melting a mixture of materials such as silica, soda ash and Calcium carbonate at high temperature followed by cooling during which solidification occurs without crystallization. Glass is a unique inert material that could be recycled many times without changing its chemical properties. Using glass in concrete is an interesting possibility for economy on wastage disposals. The inclusion of fly ash in glass concrete reduces the alkali silica reaction and improves the workability and durability properties of concrete. Sheet glass aggregate used in concrete making leads to green environment. The objective of Present work is to find out the effectiveness of the fly ash and glass aggregate based concrete. In this investigation it was proposed that the use fly ash as cement replacement material and glass aggregate as fine aggregate material partially in concrete. Natural sand was partially replaced (10% 20% 30%) with sheet glass aggregate. Compressive strength of cubes at 3days, 7days and 28 days of duration were studied. Fineness modulus, specific gravity, moisture content, water absorption was also studied. Based on the test results, the ideal percentage of mix which shows maximum compressive strength was identified
