The Effect on Leachability and Indoor Air Quality by Incorporating Waste Material into Fired Clay Brick

Abstract:

Recently waste material pollution is a critical issue in every developing country. The factors such as increasing of growing population, daily and industrial activities will lead to these phenomena. These issues give an idea to use waste as a construction material that will give minimum impact towards the environment. Many researchers have been studied on waste material such as organic waste, sludge, fly ash, rice husk and processed waste tea into fired clay brick. In this study, the investigate on the incorporating of cigarette butts (CBs) was conducted. During this study, different percentages of CBs (0%, 2.5% and 5.0%) were added into fired clay brick. Meanwhile, different heating rates were applied during the firing stage, which are 1°C/min, 3°C/min and 5°C/min respectively. All samples were fired up to 1050°C. Leaching tests were carried out to investigate the possibility of heavy metals leached from the manufactured brick. The results demonstrated that, in terms of physical and mechanical properties, CB Brick (2.5%) at 1°C/min improved the most and leached low heavy metals. For IAQ test, CB Brick (2.5%) fired at 1°C/min is acceptable to be used as building materials since it complied with ICOP-IAQ.
