LITRACON :
Light transmitting concrete
LiTraCon (“light transmitting concrete”) is a building material made of fine concret with 5% by weight of optical glass fibers which allows light transmission.
The days of grey concrete has over. The Hungarian architect has combined the concrete with optical fiber to create LITRACON.
The Allegedly, for example, can be as a silhouette of the tree, and to display a view of the outside world, wall made of “LitraCon”, has the embedded array of glass fiber and strength of concrete traditional . To form a matrix, thousands of optical glass fibers, running parallel to each other between the two main surfaces of all blocks. Shade lighter side will appear in sharp outline a dark one. But, the color does not change. This special effect creates the general impression that disappeared weight and thickness of the concrete wall. The new material, hope, is that going to change the appearance of the interior of the concrete building by letting it feel spacious and bright they are rather dark, than heavy. And to operate without any loss in the light of up to 20 m maximum, build wall structure, can be a couple of meters thick of a light-transmitting concrete fiber. Glass fibers, does not adversely affect the high compressive strength which are familiar in the concrete load-bearing structure may be constructed from the block. It can be made in various sizes with a thermal insulating block is also embedded. Forming a matrix between the two main surfaces of each block, thousands of optical glass fibers run parallel to each other. (4%) percentage of the fibers, very small compared to the total volume of the block. In addition, these fibers, and concrete exchanges, littlest their size, they become structural components such as the type of modest aggregate. Therefore, the surface of the block remains homogeneous concrete. Incidentally, it is possible to manufacture panels as a prefabricated building blocks. Fiber size is small, they blend to become a component specific materials such as small pieces of aggregate. In this way, materials and glass in the mixed concrete of two, is not the only new material third is homogeneous in the main surface to the same internal structure and results.
Glass fibers guide light at a point between the two sides of the block. Because for parallel their position, optical information of the bright side of such walls does not change to the dark side, but it is displayed. Perhaps the most interesting form of this phenomenon is the display sharp shadow on the other side of the wall.
If many buildings have started using this technique, more may be used in offices and shops are more natural light. Of course, they because it should be lit during the day, this can lead to excessive power used to greatly reduce the building of light. Also, happy in general, people who gain exposure to the sun is a more productive, as is another reason to use this light-transmitting concrete companies.
