Abstract

Photoluminescence is revolutionizing construction, especially in concrete pavements and structures, by offering both aesthetic and functional improvements. Photoluminescent pigments, which store and emit light, can positively influence the physical-mechanical properties of concrete. This study examines pigments such as strontium aluminate, zinc silicate, zinc phosphate and calcium fluorescence, evaluating their emission life and their impact on the compressive strength and durability of concrete.

Photoluminescent pigments absorb light energy and release it in the form of visible light, providing prolonged luminescence. Strontium aluminate stands out for its high intensity and durability, significantly improving the compressive strength of concrete. Zinc phosphate also offers long emission and is highly resistant to moisture. Zinc silicate improves wear resistance, while calcium fluorescence reinforces the cohesion and resistance to heavy loads of the concrete. Selecting the ideal pigment depends on the specific needs of the project.
