Study: Gemstone Waste Boosts Cement's Conductivity, Cuts Emissions
A groundbreaking study, published in AIP Advances, explores the potential of gemstone polishing waste as a sustainable additive to cement. The research, conducted by scientists from the University of Wuzhou and Guangzhou University, offers a novel approach to reducing the environmental impact of the tungsten industry.
The study, available at DOI: 10.1063/5.0295026, investigates the effects of gemstone polishing waste on cement at molecular, microscale, and macroscale levels. The researchers discovered that adding this waste significantly enhances thermal conductivity and reduces electrical resistivity in cement. The key component, silicon carbide, used in gemstone polishing, is being explored as a potential alternative to reduce cement's environmental impacts.
The study also highlights the potential of gemstone polishing waste as a means to keep waste out of study islands and reduce emissions. The researchers plan to optimize gemstone polishing waste-cement blends, ensure long-term durability, perform field tests, and explore the application of this process to other types of waste. Large amounts of silicon carbide waste are produced by the gemstone processing industry, including in Guangdong Province, making this a promising avenue for waste management and sustainability.
The study demonstrates that silicon carbide-enhanced cement could potentially be used in smart materials for energy-efficient panels or embedded sensors in structures. This innovative approach to cement production not only addresses the challenge of waste management but also offers potential improvements in the performance and sustainability of cement-based materials.
