In 2024, a group of scientists from the University of Mining and Geology won third place in the Science Innovation Contest for their research on creating concrete that transmits light using waste fly ash and slag from a waste-burning power plant. The team, led by Associate Professor Dr. Mai Anh Tuan, developed an innovative product that combines glass to create a unique type of concrete that does not use cement.
The “green” concrete products have good light transmittance, high strength, and are made from waste materials such as ash, slag, and glass. This environmentally friendly concrete eliminates the need for cement, reduces the production of toxic gases, and minimizes the impact of waste disposal. The team aims to utilize industrial waste more effectively and create a sustainable construction material that addresses the scarcity of green materials in the industry.
The research team plans to implement the project in 2021 to further reduce the pressure on waste treatment and promote the use of industrial by-products. The light-transmitting concrete panels are thin sheets with a polished surface, created by combining fly ash waste, furnace bottom slag, water filtration plant sludge with waste glass beads. The products have good mechanical properties and can withstand high compressive strength.
While there are limitations to this product such as not being able to create light patterns, it is suitable for use in decorative structures in construction projects. The research has received praise for its innovative approach to reusing waste materials and contributing to sustainability in the construction industry. Dr. Hoang Minh Duc from the Institute of Construction Science and Technology suggests further research into the interaction mechanisms between components and optimizing the technology for specific applications.
The research team’s solution for producing light-transmitting green concrete won third prize at the 2024 Scientific Innovation Contest. They plan to continue refining the product and exploring new manufacturing methods to improve its performance and market appeal. The project has been recognized for its contribution to sustainable construction practices and its potential for creating unique architectural effects through the use of light-transmitting concrete panels.
