The gap between studies examining the effect of using different ratios of optical fibers on the material strength and on energy-saving concluded that the proper ratio of fibers should be less than 5% for strength, and the optimum ratio ranges 4.3% to 6% for energy-saving.
Translucent concrete' strength and proper ratio of fibers are key limitations. Notwithstanding the advantages, literature concurs that several gaps were found in translucent concrete studies. We reviewed the remarkable studies carried out especially last 10 years in translucent concrete techniques. This paper aggregates and reviews the previous studies in terms of translucent concrete' applications, proper ratio and arrangement pattern of optical fibers, light-transmitting, mechanical, thermal and energy-saving properties. Translucent concrete (TC) or light-transmitting concrete (LTC) is produced as one of those innovative types of materials which allows external light to transmit through interior spaces by using some light elements like optical fibers with concrete.

Meanwhile over in eastern Europe, the newly renovated Bank of Georgia headquarters building features almost 300 square meters (3,229 square feet) of translucent concrete made by German manufacturer LUCEM, including LED-lit wall panels. By day, the square's sidewalk looks as though it were made of ordinary concrete, but the translucent surface lights up at night when the colored lights beneath the surface illuminate.
One of LiTraCon's first public uses, for example, was in a public square in Stockholm, Sweden. Since its development, translucent concrete has been used to create partition walls, stairs, decorative tiles and even lamps. While the glass and plastic fibers imbedded in the material make it cost-prohibitive in many large-scale construction projects, LiTraCon and other types of light transmitting concrete are finding their way into a smattering of structures around the globe. With its light-transmitting properties, however, translucent concrete has the power to potentially transform the interior of concrete buildings, making them appear fresh, open and spacious. Now you know what translucent concrete is, but how - exactly - is it used? Read on to find out.ĭrab, dull and depressing, concrete has long been associated with penitentiary-like office buildings, ugly patios and unfinished basements. The parallel fiber strands create two distinct grain-type surfaces: one bright and the other dark. The concrete is then cut into individual blocks (the smallest are about 48 x 14 inches, or 1.22 x. Here, the manufacturer hand-molds large pieces of concrete, embedding thousands of strands of optic fiber in the material at the same time. The light transmitting material is largely believed to have been invented by Hungarian architect Aron Losonczi, who began developing pre-fabricated translucent concrete blocks he called LiTraCon ( light transmitting concrete) in 2004, just three years after graduating from Budapest's Technical University.

Despite this clarity, however, translucent concrete retains its stout, crack resistant, load-bearing quality Through the resulting translucent panels, a viewer can clearly see the outline of an object on the opposite side of the concrete. The fibers are mixed with traditional concrete components - water, sand and cement - and are distributed evenly throughout the surface. The fiber strands, which attract and transmit both natural and artificial light, make up about 5 percent of a translucent concrete block's surface volume. Translucent concrete isn't exactly "see-through," but the new building material draws on optical fibers to transmit light through it while retaining the density that has literally made concrete the cornerstone of buildings around the world. While Marley's short stint as a factory worker yielded this gloomy look at life surrounded by concrete, the traditionally dim building blocks are getting a makeover designed to finally let some light shine in. That is, of course, except for a lack of sunlight.
Slum life, political strife, an absentee father there's little that could keep reggae superstar and eternal optimist Bob Marley down.
