This project utilizes innovative techniques to combine high-activity slag, steel slag, fly ash, and low-activity coal gangue, red mud, lithium slag, and other industrial solid wastes as primary raw materials. It achieves this by incorporating advanced alkali activation technology, resulting in high-performance concrete materials with a stable polymer network structure.

This material not only meets the international standards in performance indicators, but also achieves efficient and large-scale consumption of industrial solid waste, providing a practical path for China's key industries to achieve solid waste resource utilization and industrial carbon dioxide reduction.

According to the project team, the technology has broad application prospects and significant environmental benefits in the thermal power and metallurgical industries.

"The award is a high recognition of the scientific research and innovation capabilities of Guizhou Green Industry Technology Institute. We will continue to deepen technology iteration and market promotion, and contribute to the national 'dual carbon' strategic goals," said an institute representative.
