Properties of Matrix for Reducing Fine Dust According to Replacement Ratio of Bentonite

Abstract

One of the global issues documented entails fine dust reduction, which has been experimented recently. In humans, fine dust is problematic because it causes diseases. This study employed the techniques of circulating fluid bed combustion boiler fly ash and blast furnace slag as binders. Regarding fine dust reduction, the study incorporated Bentonite, which exhibits adsorption features. Indeed, indoor air pollution arises from the dominance of fine dust. Some of the parameters that were examined included fine dust concentration, water absorption, density, flowability, compressive strength, and flexural strength. With an increase in the bentonite replacement ratio, there tends to be an increase in absorption, while the density increases. The bentonite’s porous nature has been perceived to account for this behavior. In this study, it was established further that as ben-tonite’s replacement ratio increased, there was a decrease in flowability. Additionally, there was an increase in the air content with an increase in bentonite’s replacement ratio. It was also noted that the fine dust’s adsorption performance for each minute increased with an increase in bentonite’s replacement ratio. The findings were attributed to the affirmation that with an increase in the porous bentonite’s replacement ratio, there tends to be an increase in fine dust amount adsorbed for each unique surface area. There is a need for further research in which experimentations need to focus on finishing materials and how indoor air quality could be improved.
