The bricks are manufactured from natural clay, which is obtained from agricultural land. Excess usage of agricultural land for this clay results in loss of good fertile quality of soil and diversion of agricultural land for brick manufacturing. The modified Fly Ash bricks are an alternative for the conventional bricks which can be used effectively to replace the conventional bricks. In this research study, different amount of fly ash has been used in the three different mix to make fly ash bricks. In this mix the quantity of fly ash replace with the dust, Amount of fly ash is increases and the quantity of dust is decreases in the mix of fly ash brick. Quantity of lime is added in the fly ash brick of different percentages of 5%, 10% and 15%.. The maximum compressive strength of the brick is observed 7.95 N/mm2 at 40% fly ash, 15% lime and 35% dust. If the amount of lime percentages increases and amount of dust becomes decreases, compressive strength results of fly ash brick shows best results at 40% fly ash. Minimum compressive strength has been shown in the mix of 20% fly ash because the amount of dust is more as compared to fly ash. Compressive strength is also increases at 60% fly ash, 15% dust and 15% lime which amount to be 3.80 N/mm2.The optimum compressive strength is getting at 40% addition of fly ash
