2.  Light transmitting concrete(litracon) also known as translucent
concrete, 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.

3.  In 2001 the idea of transparent concrete was
put forward by Hungarian architect
Aron Losonzi.
 Successfully produced the first transparent
concrete block in 2003,named LiTraCon.
 In 2004, he started a German company
named LiTraCon and started producing
Litracon commercially.

4.  Translucent concrete works based on “Nano-Optics”.
 Fibers are placed directly on top of each other.
 Fibers acts like slits and carry light through it.

5.  Flexible, transparent fiber made up of glass or plastic.
 It transmits light between two ends of the fiber.
 Optical fiber transmits light so effectively that there is almost no
loss of light conducted through the fibers.

7. Total Internal Reflection
 When a ray of light travels from a denser to a rarer medium such
that the angle of incidence is greater than the critical angle, the ray
reflects back into the same medium this phenomena is called total
internal reflection.
 In the optical fiber the rays undergo repeated total number of
reflections until it emerges out of the other end of the fiber, even if
the fiber is bent.

9.  Cement: Ordinary Portland cement is used for
transparent concrete.
 Sand: The size of sand should pass through
1.18mm sieve.

10.  Water: Water to be used for transparent
concrete should be of drinking water
quality.
 Optical fibers: Thickness of the optical
fibers can be varied between 2 µm and 2
mm.
10

11.  The manufacturing process of transparent concrete is almost same
as regular concrete.
 Small layers of the concrete are poured into a mould and fibres are
infused in it.
 Newer, semi-automatic production processes use woven fibre
fabric instead of single filaments.
 Fabric and concrete are alternately inserted into moulds at intervals
of approximately 2 mm to 5mm.
11

12. Another method-
 Many holes are punched on side walls of the mould.
 Optical fibres have to be run through these holes from one end to
the other.
 Concrete is poured into it.

strength of OPC and LTC

15. MATERIAL PERFORMANCE:
 Concrete retains its strength
 Frost and de-icing salt resistant.
 Fire protection.
 Highest UV resistance.

16.  Energy saving can be done by utilization of transparent concrete in
building.
 It has very good architectural properties for giving good aesthetical
view to the building.

17. Transparent concrete blocks is
suitable for :
 Floors
 Ceiling
 Pavements
 Load-bearing walls
 Partitions wall

Sillhouttes of trees
Panels illuminate in different colours

18.  In furniture for the decorative and aesthetic
purpose.
 Light sidewalks at night.
 Increasing visibility in dark subway stations.
 Lighting indoor fire escapes, in the event of a
power failure.
 Illuminating speed bumps on roadways at night

19. 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.

21. 3) NEW HEADQUARTERS OF BANK OF GEORGIA:
 Walls, walks, receptions, offices and consultation desks are
illuminated by transparent concrete

22. 1)Very high cost about $1000/m2.
2) Labours with technical skills are needed to use it
22

23. ◦ Light transmitting concrete is an emerging trend in concrete
technology.
◦ Its initial cost is high. But, routine maintenance is not required and
in long run it may be advantageous. In fact it worth the cost.
◦ It’s a green building material reducing the lightning cost during day
time. It’s proved to provide both aesthetic appearance and structural
stability.
◦ In future the it’s cost is expected to decrease.
◦ It is one of the best applications of optical glass fibers which is
related to technical textiles.
