Energy efficient building and aesthetic view are the vital knot for infrastructure. Now engineers have developed smart translucent concrete(STC) using glass optical fibers (GOF).It can able to transmit light from one phase to the other phase of the wall. Smart translucent concrete is also known as pellucid concrete. Pellucid concrete reduces the consumption of electricity. Source of light can be taken from natural sunlight and artificial light source from LED having 20w. In this investigation, incorporating optical fibers in various diameters are 1.5 mm and 2.5 mm. Concrete cube with provision of hole for providing glass optical fiber and arranged in equal spacing of about 15 mm and 25 mm. In this experiment, analysis the performance of smart translucent concrete in the aspect of strength and luminance .The light intensity from the specimen can be measured with a help of photometer. It is an energy efficient building material innovated in recent years. © 2021 Elsevier B.V., All rights reserved.
