Light-emitting concrete from waste glass for safer and greener construction

Abstract

The Light-emitting concrete incorporating photoluminescent materials and recycled waste glass represents a novel advancement in the construction industry, offering enhanced visibility in low-light environments, reduced energy consumption, and improved sustainability. This study investigates the development, performance, and potential applications of such concrete, with a particular focus on its luminescent efficiency, mechanical behavior, and environmental benefits. Through a systematic optimization of mix proportions and curing conditions, the integration of photoluminescent powder and treated waste glass aggregates was shown to yield concrete with prolonged and intense light emission, while maintaining acceptable compressive strength. Notably, the application of microbial-induced calcium carbonate precipitation (MICP) to coat glass aggregates not only mitigated durability issues but also contributed to a more stable interface with the cement matrix. This treatment further enhances the material’s potential as a sustainable solution by extending the reuse of industrial waste and reducing reliance on artificial lighting. The results suggest broad applicability in areas such as road safety, architectural design, and urban infrastructure, where improved nighttime visibility and aesthetic integration are critical. With continued research into optimizing luminescent materials and extending long-term durability, light-emitting concrete stands as a promising candidate for advancing both the functionality and sustainability of future built environments.
