| description |
Brick is one of the man-made building materials that have been used since the early
human civilization. Due to the attractive appearance, strength and durability, it often
used for construction, civil engineering works and landscape design. This study is
focused on the effects of incorporating cigarette butts (CBs) into fired clay brick.
The investigation includes characterization, optimum percentage of CBs
incorporated, physical and mechanical properties, leachability and indoor air quality.
Therefore, clay soil samples obtained from Hoe Guan Brick Sdn Bhd were used as
control in this research while 2.5% and 5.0% by weight of CBs were incorporated
into the clay bricks for subsequent experiments. Different heating rates were used
during the firing processes which are 1
C/min respectively.
All samples were fired at 1050

also indicated that the maximum compressive strength of fired clay brick was
obtained with 2.5% CBs of fired clay brick at 1

others. The density becomes lightweight by 16% to 21% compared to conventional
bricks as the percentage of CBs increased. The thermal conductivity of the bricks
also improved from 24.6% to 46.1% with the increasing of CBs. In addition,
leachability results indicated that the leaching of heavy metals were below the
United States Environmental Protection Agency (USEPA) and Environmental
Protection Agency Victoria (EPAV) regulations. Finally, laboratory testing for
Indoor Air Quality (IAQ) revealed that CB Brick complied with the Industry Code
of Practice on Indoor Air Quality (ICOP-IAQ). |
