HOYOS MONTILLA, Ary Alain; IVAN TOBON, Jorge  and  FARBIARZ-FARBIARZ, Yosef. Transmission of visible light through mortars using fluorite as a fine aggregate. Rev.fac.ing.univ. Antioquia [online]. 2015, n.77, pp.41-47. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.n77a06.

This article presents the results of an evaluation of the optical properties of white and gray Portland cement mortars within the visible light spectrum. Eight controllable variables were studied: size of aggregate, type of cement, water-cement ratio, type of aggregate, cement-aggregate ratio, thickness of mortar, percentage of air entrained and percentage of optical fiber. A mathematical model was used to analyze the behavior of a light beam as it passes across a mortar. Three properties were measured: reflection, absorption and transmittance. A spectrophotometer and two sources of light were used. Of the eight controllable variables, thickness, aggregate size and cement type were those with the greatest impact on transmittance.

Keywords : Translucent mortars; optical properties of mortars; transmittance in mortars.
