In 2021, a group of scientists at the University of Mining and Geology in Vietnam won third place in the Science Innovation 2024 contest for developing a unique type of concrete that can transmit light using waste fly ash and slag from a waste-burning power plant. The “green” concrete developed by this team has been praised for its high strength, light transmittance, and elimination of cement usage.
The research team led by Dr. Tang Van Lam is committed to implementing their project in 2021 to reduce reliance on cement and better utilize industrial waste, such as ash and slag from power plants and metallurgy. By reusing waste fly ash, slag, wastewater sludge combined with waste glass, the group has created cost-effective green concrete products with excellent mechanical properties.
These light-transmitting green concrete panels have numerous applications in interior and exterior decoration of buildings, allowing architects to add unique effects through color and light. Although the current product lacks the ability to create light patterns, the team is focused on refining the manufacturing process to enhance light transmission.
Dr. Hoang Minh Duc, Director of the Institute of Concrete Specialization, commended the project for providing a sustainable solution to waste management and called for further research to optimize the product’s properties and market applicability. The team was awarded third place at the Science Innovation 2024 contest for their ingenuity and environmental benefits.
Overall, this innovative approach aims to minimize the environmental impact of cement production processes while addressing the scarcity of green construction materials. By utilizing waste materials more effectively, this technology offers a sustainable solution to both environmental concerns and economic challenges associated with traditional construction methods.
