A review on light-emitting concrete using waste glass aggregates: Progress, potential, and challenges

Tóm tắt

Light-emitting concrete (LEC) has recently gained significant attention as a multifunctional construction material that integrates sustainability, energy efficiency, and aesthetics. By incorporating phosphorescent powders and recycled waste glass aggregates, LEC not only emits light in dark environments but also promotes circular economy practices through the reuse of post-consumer glass. This review provides a comprehensive overview of the current research landscape surrounding LEC, including its historical development, material composition, fabrication methods, optical and mechanical properties, practical applications, and environmental benefits. Special emphasis is placed on recent innovations and experimental findings in Vietnam, where local materials and techniques have been adapted to optimize performance. Challenges such as alkali-silica reaction, durability of luminescent compounds, and the absence of standardization are critically discussed. Finally, future research directions are proposed, including smart integration with energy systems and potential for self-sensing or self-healing capabilities. The findings suggest that LEC represents a promising solution for sustainable urban development, particularly in contexts requiring low-energy illumination and resource reuse.
