Experimental and Theoretical Analysis on Thermal Conductivity of Fired Clay Bricks Incorporated with Cigarette Butts
Currently higher requirements in thermal performance is needed for the quality of building materials especially fired clay bricks. Thermal conductivity is an important criterion as it will influences the heat losses from building. The objective of this study is to validate the estimation value of thermal conductivity by using theoretical value with the experimental work conducted in the laboratory. The experiment data was collected in order to compare with a theoretical model that obtained the thermal conductivity value based on it relationship with dry density of fired clay bricks. Different percentages of CBs (0%, 2.5% and 5.0%) were incorporated into fired clay bricks. Different heating rates were applied during firing stage, which are 1°C/min, 3°C/min and 5°C/min respectively. All samples were fired up to 1050°C. The experimental work for thermal conductivity was carried out using the Hot Guarded Plate Method. Meanwhile, the theoretical result was obtained from the previous study using model developed. Throughout statistical analysis, some trend of thermal conductivity and dry density were revealed. The analysis results show that as the dry density decreased, thermal conductivity also decreased.
