3. INRODUCTION
 Transparent material means which can be seen from one
part to another part.
 Light transmitting concrete(LiTraCon)also known as
translucent concrete,is a concrete based building material
having light transmissive property.
 It is a new technique different from normal
concrete.Translucent concrete allow more light and less
weight compared to normal concrete.
 Light transmissive property mainly due to uniform
distribution of optical fibers throughout its body.
 It is available as prefabricated building blocks and panels.

4. HISTORY
 In 2001,the idea of transparent concrete was found by
Hungarian Architect Aron Losonczi.
 In 2004,he started a German company,named LiTraCon
and started producing LiTraCon commercially.

5. MATERIAL USED FOR TRANSLUCENT
The two basic materials used for making transparent concrete:-
1.Fine concrete
2.Optical fibres
 Fine Concrete:- Consist of cement and fine aggregate such as
sand and instead of coarse aggregate optical fibers are used.
 Optical fibers:-1) An optical fiber is a thin cylindrical fiber
made of glass.
2)Its function is to guide visible infrared light
over long distances.
3)It has three parts:-a)Core
b)Cladding
c)Buffer coating

7. WORKING PRINCIPLE
 Transparent concrete works on “Nano-Optics”.
 The principle behind the transmission of light in an optical
fibre is total internal reflection.The light should incident at
an angle greater than critical angle.
 In the optical fiber the rays undergo repeatedly untill the
total number of reflection run out to the ther end of the
fiber even if the fiber is bent.

8. MANUFACTURING PROCESS
 The manufacturing process of transparent concrete is
almost same as regular concrete.
 Small layers of concrete(with a ratio of 1:2 for mixing) are
poured into the mould and on top of the each layers,a layer
of fibers is infused.
 Fabric and concrete are alternately inserted into moulds at
intervals of apporximately 2mm to 5mm.
 Another Method:- 1)Many holes are punched on side
walls of the moulds.
2)Optical fibers have to run through
these holes from one end to another.Clay is used to
withstand optical cables for support and concrete is poured
into it.
 Adding 4% to 5% optical fibers by volume in to the
concrete mixture.

9. EXPERIMENTAL SETUP
 Choosing a desire mould
 Make a needed design
 Attach clay on the bottom of the mould
 Induce optical fiber cables at desired shape
 After that pour fine concrete at its approximate ratio
 Set to dry and allow to curing
 Finally we get the transparent concrete in desire shape

10. ADVANTAGES AND DISADVANTAGES
 Advantages:- 1) Energy saving can be done by utilization
of transparent concrete in building.
2) It has very good architectural properties
for giving good aesthetical view to the building.
 Disadvantages:-1) Very high cost.
2) Skilled labours required.

11. APPLICATIONS
 Transparent concrete blocks is suitable for:-
 1) Floors
 2)Ceiling
 3)Pavements
 4)Partitions wall
 Examples:-a)The Europe Gate
b)Cella Septichora,Pecs,Hungary
c)New Headquaters of Bank of Georgia

12. CONCLUSION
 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.
 It is a green building material reducing the lightning cost
during day time.It is proved to provide both aesthetic
apperance and structural stability.
 In further its cost is expected to decrease.
 It is one of the best applications of optical glass fibers
which is related to technical textiles.
