Study on properties of self-lighting cement pavement material

The paper investigated the influence of luminescent sand and reflectance powder on the workability, mechanical properties, and luminescence performance of cement-based material. The results showed that adding luminescent sand and reflectance powder decreased the consistency and fluidity of the mixture. Furthermore, incorporating these materials can enhance the mechanical strength of self-luminous samples. Nevertheless, exceeding 40% in the content of luminous sand or surpassing 10% in the content of reflective powder will reduce its strength. Furthermore, the initial brightness of these materials can reach 0.82cd/m2, and the afterglow time can reach 12 h when the luminous sand content is 50% and the reflective powder content is 20%. These results indicate that luminescent sand and reflective powder can improve the luminescence properties of cement-based materials. The incorporation of luminescent sand optimises the distribution of hydration products, enhancing the luminescence performance of the cement-based materials. These research findings will provide new insights for the design of road surfaces in low-light environments.
