FLOR, Margarita; CARPIO, Andrés  e  SANTAMARIA, Jorge. Estudio de un compuesto cementante fotoluminiscente y su aplicación en la construcción. Figempa [online]. 2018, vol.5, n.1, pp.62-70. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v1i1.811.

Nowadays, the need to develop materials that promote efficient energy savings has been one of the transcendental topics studied around the world. With this novelty, the present investigation determined that the inclusion of Strontium Aluminate co-doped with Europium and Dysprosium in binders based on Portland cement not only produces the photoluminescence phenomenon but also improves its mechanical properties; through the accomplishment of diverse physical-mechanical laboratory tests like the compressive strength in test pieces, besides chemical analyzes with XRF in different samples of concrete. The research further found that the 0.3:1 ratio of the compound to the cement allow obtaining the most optimal phosphorescent effect. Finally, by means of the economic analysis it is shown that the cost/benefit of applying the photoluminescent cementitious composite as a long-term road sign is much more cost effective than the use of the conventional luminaire.
