This work aims to study the feasibility of applying luminescent material on transparent recycled glass aggregate (RG) for the production of decorative architectural mortar. The luminescent-glass aggregate (LGA) was prepared by coating mixtures of luminescent powder and transparent adhesive paint on the surface of RG with different particle sizes (2.36∼5 mm and 5∼10 mm), and their impact on the properties of architecture luminescent-glass mortars (ALM) was studied. The results indicated that the ALM possessed 27–30 MPa compressive strength and 6–7 MPa flexural strength meeting most architectural and building applications. The 28-day compressive strength of ALM was lower than that of the control sample (GA without luminescence) due to the retarded cement hydration caused by the adhesive paint. However, ALM performed better in terms of shrinkage and resistance to alkali-silica reaction in particular with larger size of LGA, because the presence of a coated layer of luminescent powder can prevent the contact between silica and alkaline phase. Most importantly, the luminescent surface emitted yellowish-green light (glow) and maintained an appropriate brightness for 8 h in a dark environment.
