PERFORMANCE EVALUATION OF INTERLOCKING BRICKS USING GRANITE WASTE POWDER

This paper mainly focus on utilisation of industrial wastes in making interlocking building brick, Flyash and Granite industry generate large amount of solid waste, the disposal of this waste creates environmental problems and health hazards. The study involves the experimental investigation of effect of varying proportion of granite waste powder and lime in the fly-ash in making flyash based interlocking brick and to analyses the properties of interlocking bricks such as compressive strength and water absorption. Three different types mix proportion were prepared, for first mix proportion with fly-ash with (85 to 65)% ,granite waste powder (5 to 25)% and lime 10% were used as raw materials for production of interlocking bricks, for second mix proportion with flyash with (73 to 65)% ,granite waste powder 25% and lime (2 to 10)% were used as raw materials, for third mix proportion with fly-ash with 60% ,granite waste powder (10 to 30)% and lime (30 to 10)% were used as raw materials, after casting the fly ash based interlocking bricks for varying different proportions, these interlocking bricks were sun dried and then tests was carried out on the interlocking bricks, for 7 and 21 days compressive strength and percentage of water absorption was determined.
