Experimental Study on Low Density Brick (Cenosphere Bricks)

Abstract

A flyash bricks can be extensively used in all types of building construction activities. Our project was based on low density brick, using cenosphere material. The cenosphere bricks may be comparatively lighter in weight and stronger than common flyash bricks. Since cenosphere is being accumulated as waste material in large quantity in thermal power plants and creating serious environmental pollution problems. Flyash is replacing to cenosphere of flyash bricks with proportion as using specimen size 230mm x 100mm x 75mm were cast for mix percentage of cenosphere(60%), OPC(10%) and Quarry dust (30%). The results shows the variation of compressive strength and water absorption for mix proportions of materials mentioned earlier at curing ages. Then we may consider the specimen size 230mm x 100mm x 100mm to casting the bricks of different mix proportions to the percentage of cenosphere (15 to 50%), OPC (5 to 35%) and Quarry dust (20 to 55%).We had tested various specimen as per proportion considered for casting. After this, we compared the weight, compressive strength and water absorption of cenosphere with different proportion of flyash bricks.
