ESTUDO SOBRE ARGAMASSA FOSFORESCENTE: PROPRIEDADES ÓPTICAS E APLICABILIDADE NA CONSTRUÇÃO CIVIL

Abstract

The innovation in the Civil Engineering materials area seeks to answer environmental, economic and constructive issues for the sustainable development and the use of resources. The researches on materials with luminescent properties with lighting, aesthetics, architecture and energy saving functions are examples in new technologies. Among them, the phosphorescent mortar, which allows different uses and employments – composed of white cement and photoluminescent pigments that enable the absorption, storage and reflection of light in a slow and durable way. The present research analyzed the optical properties of this type of mortar, considering its functionality, applicability and cost-benefit for civil construction. The experimental program included samples of different concentrations of pigments (green and blue colors) and laboratory tests (Night illuminance test and Luximeter device test). Finally, it was verified the samples night illumination and the luminous flux increase in proportion to the concentration of pigments. The illuminance values showed aptitude for safety and emergency signs, although below the minimums for indoor lighting. Furthermore, the high cost-benefit of the material presented that the phosphorescent mortar are profitable for use on a small scale in civil construction.
