Translucent concrete is a concrete based on building material with light-Transmissive properties due to embedded light optical elements usually Optical fibers and glass powder. It is lighter than conventional concrete having special features such as low density and thermal conductivity with main advantage of reduction in dead weight, faster building rate in construction and handling cost. An optical fiber is a flexible transparent made of glass or plastic, slightly thicker than a human hair and can function as a wave guide to transmit light between the two ends. Recently, the concept of green architecture has become a common interest in various disciplines. Innovative materials are continuously developed to fulfill the green architecture requirements. Translucent Concrete is a new type of Concrete used widely in the construction industry. The main purpose of transparent concrete is to use sunlight as a light source to reduce the power consumption of illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an architectural purpose for good aesthetical view of the building. The Light is conducted through the stone from one end to the other. Therefore, the fibers have to go through the whole object. Translucent concrete is also known as the transparent concrete and light transmitting concrete because of its properties. It is used in fine architecture as a facade material and for cladding of interior walls etc. The concrete considered is cement mortar which contain fine aggregate and cement. The fibers are placed in shortest direction to increase the transparency of concrete. In this paper, to integrate the merits of concrete and optical fiber, for developing transparent concrete by arranging the high numerical aperture Plastic Optical Fibers or big diameter glass optical fiber into concrete. The size of optical fiber will vary between 2μm and 2mm. in order to increase the transparency of concrete the same amount of cement is replaced by fine glass powder. The binding capacity of glass powder and cement are same. The specimen casted will contain 95% of concrete and 5% of plastic optical fibres. We reviewed the remarkable studies carried out especially last 10 years in translucent concrete techniques.
