The objective of this research was to study the effect of bagasse and bagasse ash on the properties of pottery products. In the experiments, we varied the composition of clay by adding 2%, 4%, 6%, and 8% by weight of bagasse or by adding 5%, 10%, 15%, and 20% by weight of bagasse ash and maintained the temperature of the furnace at 900 °C. The results indicate that the best composition is obtained by adding 10% by weight of bagasse ash, which yielded pottery products with improved strength (20.10 MPa), density (1.41 g/cm3), water absorption (13.91%), and porosity (25.73%). In comparison, the composition of clay with 4% by weight of bagasse yielded strength, density, water absorption, and porosity of 10.12 MPa, 1.53 g/cm3, 19.95%, and 30.17%, respectively.
This research aims to study the effect of sludge from water treatment plants on the properties of pottery such as density, compressive strength, water absorption, and porosity.The composition of sludge from water treatment plants added to the clay varies, at percentages of 0%, 10%, 20%, 30%, 40%, and 50%, controlled by weight. The results showed that the composition of 10% by weight of sludge from the water treatment plant yields the ultimate pottery properties, with 12.63 MPa of compressive strength, 1.85 g/cm3 of density, 14.24% of water absorption, and 26.34% of porosity.
The objective of this study was to recycle powdered marble dust to improve mechanical properties and thermal conductivity of lightweight clay bricks. Varying amounts of powdered marble dust (10, 20, 30, and 40 vol.%) were added to a lightweight clay brick at the firing temperatures of 900, 1000, and 1100 °C. When higher quantities of powdered marble dust were added, the values of porosity and water absorption increased while those of thermal conductivity and bulk density decreased. The decrease in apparent porosity and water absorption were also affected by the increase in firing temperature. The most desirable properties of the clay bricks were obtained for the powdered marble dust content of 40 vol.% and firing temperature 900 °C: bulk density of 1.20 g/cm3, compressive strength 9.2 MPa, thermal conductivity 0.32 W/m.K, and water absorption 22.5%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
