2. • what is nanotechnology
• Classification of nanotechnology uses
_construction materials
_finishing materials
• Nanomaterial's Costs
• Pros and Cons of Nanomaterial Usage in Architecture
• Examples

3. • Nanotechnology is the use of very small pieces of material
by themselves or their manipulation to create new large
scale materials
• The use of nanotechnology in construction is strongly linked
to sustainability
 Tackle climate change.
 Help reduce greenhouse gas emissions in the
foreseeable future
• Nanotechnology offers a new technological means with
which to:

materials
• Nano Concrete
• Nano iron
• Nano-treated wood

• Self-cleaning breaks( down carbonic and organic
compounds into hydrocarbons, which are environmentally
friendly,)
• anti-ultraviolet,
• anti-bacterial,
• anti-fungal.

6. 2 carbon nanotubes 3 4

• Increase the mechanical resistance of various
elements

7. 3 Nano silica 4 5

• We are increasing the mechanical resistance of various
elements and improving the
• plasticity,
• flexibility,
• shrinkage of concrete and cement.

8. 4 Nano aluminum 5 1

• Increase wear resistance and rust resistance

9. 5 polycarboxylate 4 3
2 1
• Polycarboxylate (PCE) are used as super plasticizers in
concrete production.
• It can also be used in constructing marine structures

10. Finishing
materials
• Glass
• Coatings and Paintings

12. • A gram of nanotubes could cost several
thousand dollars; even recently, 500 or so
dollars per gram was a common price
• Costs for Nanomaterials products are also high
• Nano Silica Silicon Dioxide Powder SiO2
Price For Coating it costs about 48.00 $

13. cons
• Improving pipe joining materials
and techniques
• Better properties of cementations
materials
• Reducing the thermal transfer rate
of fire retardant and insulation
• Increasing the sound absorption of
acoustic absorber
• Increasing the reflectivity of glass.
• Nano particles being very small in size have
the potential to negatively affect the
• respiratory and digestive tracks and the skin
or eye surface thus exposes workers
and even users to hazards.

Using TiO2-coated tiles
The facade is comprised by Prosolve 370e tiles, a material that has a superfine coating
of titanium dioxide, a photocatalytic substance that captures and neutralizes the smog
particles. This process requires sunlight and, for this reason, the form of the tiles was
optimized in order to receive the maximum possible amount of sunlight all along its’
surface.
