2. Introduction
Self cleaning or depolluting photo catalytic concrete, by the
name itself it shows its affordability.
The name that it looks like futuristic ideas and some of us may
think that it is possible.
But it is practical now, many foreign countries are stick to the
concrete for its unbelievable beneficial results.
3. Luigi cassar(the innovative
inventor)
Luigi cassar( Italian chemist) invented the self cleaning
concrete in 2013.
Got European inventor award in 2013.
He invented the fabulous concrete in italicement.
4. Nitrogen oxide(the foreign intruder)
Nitrogen oxide NOX is the air pollutant which presents in
the atmosphere more amount due to smog, smoke,
vehicle, emission etc.
5. Why titanium dioxide(TiO2)
Titanium dioxide is the only component which makes
the building effectively non polluted.
TiO2 through its process of oxidizing the NOx into NO
andNO2 in powdered form it makes the building
depolluted.
6. The mix design
Similar to m20 grade concrete.
Addition of 3.5% to 4% of Tio2 to the 96.5%of
cement.
Without any other chemical admixtures.
7. Procedure to be followed
Light and heat are the main source.
Make sure these hits the concrete.
Automatically the reaction takes place.
Then the gaseous particle break down into dust particle.
Rinse it with water to make it clean.
8. The operation of self cleaning
concrete
Once the sunlight is falls on the building the UV rays of
certain range will allowed to fall on the building.
Photocatalytic process Tio2+Nox+sunlight.
The hazardous gas becomes powdery particle and stays
over the building like a dust.
9. After the process
Water plays main role as a source of rain fall or manual
cleaning.
So clean the concrete with the water.
Or otherwise it was self cleaned by rainfall and makes the
building non polluted.
Water droplets rinsing the NOx dust.
11. Tunnels and pavements
Tunnels are most denser atmosphere.
Due to this larger air pollution occurs by vehicle.
UV lamps are used here as source.
As well as pavements also provided by self cleaning
concrete.
14. Merits of self cleaning concrete
Reduces NOx content in atmosphere.
Keeps the concrete young.
Depollute other pollutants.
Eco friendly.
Reduces depletion of ozone layer.
Reduces corrosion and patch formation in the concrete.
15. Conclusion
Photocatalytic concrete materials have been used in horizontal
and vertical applications.
Inventors are the one who invents and engineers are the one
who makes it comfortable to the environment.
Using the articles like self cleaning concrete it is possible.
It is preferable to use self cleaning concrete as an ecofriendly
approach.
