Abstract

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.
