Translucent concrete, also known as light transmitting concrete, is a concrete-based building material that has light-transmissive properties due to the uniform distribution of optical fibers throughout its body. It was invented in 2001 by an architect who was inspired by an art installation combining concrete and glass. Some advantages are its ability to transmit light, improved strength over conventional concrete, and good aesthetic and architectural qualities. However, it has higher costs due to the optical fibers and requires skilled labor for casting. Applications include floors, walls, pavements, and illuminated structures like speed bumps. Existing structures using this material are The Europe Gate statue in Hungary and a door made of translucent panels at a site in Pecs, Hungary.

2. HISTORY
Light Transmitting concrete was invented by an architect from Hungry named Aron Losonczy when he saw an art at
Budapest, which was made up of ordinary concrete and glass.
This gave thought of combining the two materials together. In 2001, successfully a light transmitting block was produced.
Aron Losonczy named his invention as “LITRACON”, which said as light transmitting concrete, in 2004, he started a
German company named Litracon. and started producing Litracon commercially.
As the pioneer of translucent concrete, Losonczi was able to successfully produce the first transparent concrete
block within two years of pitching the idea. This new material was called LiTraCon (short for Light Transmitting
Concrete), and soon became popular in countries including Italy, Germany, and even China.

3. INTRODUCTION
Light transmitting concrete (Litracon) also known as translucent concrete, it is a concrete based building material having light-transmissive property.
Light-transmissive property is mainly due to uniform distribution Optical Fibers throughout its body. It is also known to be transparent concrete.
It is available as prefabricated building blocks and panels
Translucent concrete (also: light-transmitting concrete) is a concrete based building material with light-transmissive properties due to embedded
light optical elements — usually optical fibers. Light is conducted through the stone from one end to the other. Therefore, the fibers have to go
through the whole object.

4. ADVANTAGES
1. Ability of light transmittance.
2. Betterment in strength than
conventional concrete.
3. Good aesthetical & architectural
properties.
DISADVANTAGES
1. Cost-effective due to the optical fibres.
2. Casting of concrete block is very difficult for labours,
so special skilled person is required

5. APPLICATIONS
1. These fibre reinforced concrete blocks suitable for floors, stairs, pavements, both
interior & exterior walls.
2. For construction of underground buildings & improving visibility for subway stations.
3. Illuminating speed bumps on roadways & also in light sidewalks at night.
4. In furniture & tiles for the decorative and aesthetic purpose.

6. 1) EXISTING STRUCTURE
1)THE EUROPE GATE
It is located in Fortress Monostor in the Hungarian town, Komarom
The sun illuminates the 37.6ft large Litracon piece of the statue in the mornings and late afternoons
In night an even more impressive view can be seen because of the embedded light sources.
2) CELLA SEPTICHORA , PECS, HUNGARY
It has a door made of Litracon Panels set in a steel frame.
