What is a concrete? Classification based o state of concrete? and various tests?
This presentation gives a brief introduction on FRC's history, definition and why is it used. Types of FRC's and it's applications is explained in detail in later stages.Also, it covers various properties that affects FRC and a Case study in end.
Concrete is one of the world's widely used building material The introduction of fibre optics into the concrete mix has given it a new dimension Transparent Concrete or LiTraCon (Light Transmitting Concrete) or translucent concrete can be produced as prefabricated building blocks which is able to move light through the concrete upto 20m thickness
Recycle material used in road constructionpavan bathani
As the world population grows, so do the amount and type of waste being generated.Many of the waste produced today will remain in environment.The creation of non decaying waste material, combined with a growing consumer population, has resulted in a waste disposal crisis.
One solution to this crisis lies in recycling waste into useful products.
It is try to match society need for safe and economic disposal of waste material with highway industry need for better and more cost effective construction material.
Transparent concrete is a concrete based building material with light-Tran missive properties due to embedded light optical elements usually Optical fibres. Light is conducted through the stone from one end to the other. Therefore the fibres have to go through the whole object. Transparent concrete is also known as the translucent concrete and light transmitting concrete because of its properties. It is used in fine architecture as a facade material and for cladding of interior walls. In this paper, to integrate the merits of concrete and optical fibre, for developing transparent concrete by arranging the high numerical aperture Plastic Optical Fibres (POF) or big diameter glass optical fibre into concrete. The main purpose is to use sunlight as a light source to reduce the power consumption of illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an architectural purpose for good aesthetical view of the building.

This presentation covers the contemporary building material 'TRANSLUCENT CONCRETE' - the materials, types, properties, principle, manufacture, application, advantages & disadvantages.
Now days, a Small buildings are replaced by high rise buildings and sky scrapers. This arises one of
the problem in deriving natural light in building, due to obstruction of nearby structures. Due to this problem
use of artificial sources for illumination of building is increased by great amount. LiTraCon (light transmitting
concrete) successfully produced the first transparent concrete block in 2003, It is very essential to reduce the
artificial light consumption in structure, Since concrete is strong in compression and weak in tension and
flexure
A Study on Translucent Concrete Product and Its Properties by Using Optical F...IJMER
- Translucent concrete is a concrete based material with light-transferring properties,
obtained due to embedded light optical elements like Optical fibers used in concrete. Light is conducted
through the concrete from one end to the other. This results into a certain light pattern on the other
surface, depending on the fiber structure. Optical fibers transmit light so effectively that there is
virtually no loss of light conducted through the fibers. This paper deals with the modeling of such
translucent or transparent concrete blocks and panel and their usage and also the advantages it brings
in the field. The main purpose is to use sunlight as a light source to reduce the power consumption of
illumination and to use the optical fiber to sense the stress of structures and also use this concrete as an
architectural purpose of the building
Transparent concrete is produced by mixing 4% to 5% (by volume) optical fibers in the concrete mixture. This concrete has less weight compared to original concrete. Materials for Transparent Concrete. Transparent concrete is manufactured by using combination of fiber optics and fine concrete.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. 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 is mainly due to uniform distribution of
optical fibers throughout its body.
It is available as prefabricated building blocks and panels.
It is used in floors, pavements, ceiling, load-bearing walls,
partition walls etc.
4. HISTORY
In 2001 the idea of transparent concrete was found by
Hungarian architect Aron Losonczi.
Successfully produced in 2003, named LiTraCon.
In 2004, he started a German company, named
LiTraCon and started producing LiTraCon
commercially.

5. The two basic materials used for making transparent
concrete:
1. Fine Concrete
2. Optical Fibers
Fine Concrete: consists of cement and fine aggregate such as sand
& instead of coarse aggregate optical fibers are used.
Optical fibers:
1. An optical fiber is a hair thin cylindrical fiber made of glass or
transparent dielectric medium
2. Its function is to guide visible infrared light over long
distances.
6. 3. It has three parts :
CORE:- central tube of very thin size made up of optical transparent dielectric medium
and carries the light from transmitter to receiver. The core diameter can vary from about 5um
to 100um.
CLADDING:- outer optical material surrounding the core having reflecting index lower
than core. It helps to keep the light within the core throughout the phenomena of internal
reflection.
BUFFER COATING:- plastic coating made of silicon rubber which protects the fiber.
The typical diameter of fiber after coating is 250um -300um.
4. Three kinds of optical fiber: I. multimode graded-index fiber.
II. multimode step-index fiber.
III. single mode step-index fiber.
9. CONTINUED......
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. Transparent concrete works based on “Nano-Optics”.
The principle behind the transmission of light in an optical fiber is
total internal reflection. The light should incident at an angle greater
than the critical angle.
In the optical fiber the rays undergo repeatedly until the total number
of reflections run out to the other end of the fiber even if the fiber is
bent.
11. 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
approximately 2mm to 5mm.
Another Method-
Many holes are punched on side walls of the mould.
Optical fibers have to be 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 into the concrete mixture.
1000’s of strands of optical fibers are cast into concrete.
The casted material is cut into panels or blocks & polished typically.
12. 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.
EXPERIMENTAL SET UP
13. Finally we get the transparent concrete in desire shape.
14. STRENGTH PROPERTY
The casted material is cut into
panels or blocks of the specified
thickness and the surface is then
typically polished, resulting in
finishes ranging from semi-gloss
to high-gloss.

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.
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.
