Experimental investigation on hollowedclay brick

This paper presents the experimental investigation on hollowed clay brickto enumerate itssound insulation. A total of 90 test specimens were cast and testedwith variations for each of 6 specimens. To createthe sound insulation inside the brickby using chart paper boxes placed in the core area of brick with combustible material such as saw, rice husk and cow dung. After the process of burning the combustible materials fully burned and turned into ash.The findings of the study concluded that the sound insulation of single hollowed brick 2 -3% greater than that of ordinary brick. In double hollowed 1.5% and triple hollowed bricks was 1.9% higher than the ordinary brick.
