This document discusses light emitting concrete, which is a concrete building material that emits light through uniformly distributed optical fibers. It works on the principle of nano-optics, where fibers placed directly on top of each other act like slits to carry light through the material. The document outlines the history, properties, manufacturing process, advantages and disadvantages of light emitting concrete. Examples of its applications in buildings, sidewalks, and furniture are also provided.

3. Introduction
Light emitting concrete also known as translucent concrete
It is a concrete based building material having light emitting
property.
 Light emitting property is mainly due to uniform distribution
Optical Fibers throughout its body .
It is available as prefabricated building blocks and panels.

4. History
In 2001 the idea of Light
emitting concrete was put
forward by Hungarian architect
‘Aron Losonzi’.
 Successfully produced the first
Light emitting concrete block in
2003,named LiTraCon.
 In 2004, he started a German
company named LiTraCon and
started producing Litracon
commercially.

5. Principle
Light emitting concrete works based on
“Nano-Optics”.
 Fibers are placed directly on top of
each other.
 Fibers acts like slits and carry light
through it.

6. Optical fiber
 Flexible, Light emitting 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. Structure

8. Properties
Carries the same amount
of light through a brick & no
matter how thick it is
The light carried maintains
its original color
Weighs about the same as
conventional concrete
96% traditional aggregate
and cement, 4% fibers
It Can be manufactured in
any color upon request

9. Material used
Cement: Ordinary Portland cement
is used for Light emitting concrete.
 Sand: The size of sand should pass
through1.18mm sieve.

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

11. Manufacturing Process
 The manufacturing process of Light emitting 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.

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.

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

14. Advantages
Energy saving can be done by
utilization of Light emitting
concrete in building.
 It has very good architectural
properties for giving good
aesthetical view to the building.

15. Disadvantages
 Very high cost.
 Need of Labor with technical skills

16. Applications
Light emitting concrete
blocks is suitable for :
 Floors
 Ceiling
 Pavements
 Load-bearing walls
 Partitions wall
Sillhouttes of trees
Panels illuminate in different
colours

17. 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 Stairs

18. Examples
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.

19. 2.CELLA SEPTICHORA , PECS,
HUNGARY
It has a door made of Litracon Panels set
in a steel frame.

20. 3.NEW HEADQUARTERS OF BANK OF
GEORGIA
 Walls, walks, receptions, offices and consultation
desks are illuminated by Light emitting concrete

21. Conclusion
Light emitting 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 fibers which is related
to technical textiles.
