| Summary: | Discarded cigarette butts (CB) are a form of non-biodegradable litter. CB are
carried as runoff from streets to drains, rivers, and ultimately to the beaches
and ocean. Cigarette filters are one of the most collected items each year. This
study presented the research of incorporation of CB into fired clay brick. The
effects of the additional of CB material on the properties of fired clay brick
were investigated. Physico-mechanical properties of fired clay bricks
manufactured with 2.5% and 5.0% of CB are fired at different heating rates at
1°C/min, 3"C/min, and S°Clmin in a furnace. The properties of CB brick were
tested on compressive strength. initial rate suction (IRS). dry shrinkage and dry
density. The results from the study were analyzed and compared between CB
brick and control brick. The properties of CB brick are presented and
discussed. From the results, it shows that the values of shrinkage and IRS were
slightly increased with the increasing of CB in fired clay brick manufactured.
However, the shrinkage of brick was reduced by up to 50% depending on the
percentage of CB incorporated into the raw material. Nevertheless: the
appropriate percentage of CB addition into the mixture improved the
compressive strength value by 6.6% to 18%. On the other hand, at 3°C/min of
heating rate resulted the best properties of manufactured brick compared to
1°C/min and S0C/min. As the conclusion^ in this study 2.5% CB brick fired at
3"Clmin is the optimum condition in the brick manufacturing as it obtained the
best physical and mechanical properties. |
