The document discusses light transmitting concrete (LiTraCon), which is a translucent building material made from fine concrete with optical fibers distributed throughout. LiTraCon transmits light through total internal reflection within the fibers. It has advantages like insulation, light transmission without loss, and versatility. Applications include translucent walls, ceilings, pavement markings, and decorative furniture. While more expensive than traditional concrete, LiTraCon integrates lighting and architecture in a sustainable material.

The optical fibres are arranged in
different layers, that increases
the load carrying capacity of
concrete and also the pattern
can be created to make the
concrete decorative.

LITERATURE REVIEW

5. PRINCIPLE
• Thousands of glass optical fibres placed parallel to each other
• Light transmits from one face to another
• Concrete get shine
• Transperency depends on no. of optical fibres

6. COMPONENTES OF LITRACONCOMPONENTES OF LITRACON

+ =

7.  Fine Concrete = Cement + Sand + Water
 Cement – OPC 43 grade
 Sand – - Fine sand
- Sieved from 1.18 mm sieve
- Free from Pebbles & Vegetation
 Water : - add sufficient quantity
- to make cement mix flow
- free from impurities
FINE CONCRETE:

8. • Principle: Total Internal Reflection
• Flexible and transparent fibres
• Made up of pure glass or quartz
• Act as pipe through which light flows
• More resilient to damage
• Light transmits without loss
• Fibre is very thin hence bend without breaking

ADVANTAGES OF OPTICAL FIBRE

13. DISADVANTAGES OF LITRACONDISADVANTAGES OF LITRACON
 The main disadvantage is high cost because of the optical fibres.
 Casting of transparent concrete block is difficult for the labour so
special skilled person is required.

14. APPLICATIONSAPPLICATIONS
• Translucent concrete walls on restaurants, clubs, and other social establishments
helps to use natural sunlight on day time.
• Ceilings of large corporate buildings
• Speed breakers & Lane markers in parking lots and highways
• In staircases and inner walls during times of power cuts at night leading to a great
deal of safety.
• For subways and airports etc., this translucent concrete blocks would add to the
visibility.
• Partition walls in office cabins and houses
• Attractive furniture

15. APPLICATIONSAPPLICATIONS
• Light fixtures
• Lighting in dark subway stations
• Cladding of facade
• Ceiling
• decorating the interior of a hall or lobby
• Bookshelves
• tables and statues.

16. CONCLUSIONCONCLUSION
 The compressive strength value using optical fibers do not have much
reduction when compared to conventional concrete.
 The ratio of optical fibre volume to concrete is proportional to transmission.
 The transparent concrete not looses the strength as compared to
conventional concrete.
 These new kinds of building material can integrate the concept of green
energy saving with the usage of LITRACON
 It can be used for the best architectural appearance of the building. Also
used where the light cannot reach with appropriate intensity.
 It is a great sign of attraction and artistic evolution. The only drawback
would be its high cost.
