2. Why choose a right material???
• Ecological balance
• Green building material
• Economical structures
• Faster construction
• Aesthetic advantages

3. 1.ETFE-Ethylene Tetrafl Uoroethylene.
• A fluorocarbon based polymer.
• After ETFE is heatedup and extruded
into a paperthin film,it can be welded
into largesheets that can be
themselves beused as building films
orcan be woven as pumped air
cusions.
• When ETFE arefused into pillows and
pumped with air,the materials take on
both stability and high insulation
properties.

4. • TheseETFEsheetsare transparent
likeglassandtrasmitmore light
thanglass.
• Cost24%to70%lessthanglassto
install.
• ETFEsheetsare chemicallyinert,so
theydontdegradeunderUVrays.
• Asithastefloninit.Itis

• Recyclable:Attheendoftheuseful

5. Asthetics:
• One canmanipulate the layers
in cusions to change the
insulatingcalculations.You can
print graphics onto it to avoid
the sunlightpenetration.
• By printing patterns on different
layers,one can create
kaleidoscopes that change and
react to sunlight.

6. 2.Lucem Translucent concrete: LED concrete
• Translucent concrete(light emitting
concrete) is a concrete based
building material with light-
transmissive properties due to
embedded light optical elements-
usually optical fibres.
• Themanufacturing process of
transparent concreteis almost same
as regular concrete.Only optical
fibres are spread throughout the
aggregateand cementmix.

7. • Translucentconcrete is used as fine
architecturalfacade material and
also for cladding of interior walls.
• It can be also usedfor
flooring,ceiling,wall mounting etc...

8. 3.Glassfibrereinforcedconcrete:GRC
• Glassfibre reinforced concrete or GRC is a
composite material comprising a mixture
of hydraulic cement,silica sand,alkali
resistant glassfibres and water.
• The glass fibres in GRC effectively
reinforce the mortar mix thereby
improving its tensile strength and
characteristics.

9. • Applications
1.Architectural cladding
2.Architectural moulding
3.Building components
4.Industrial products
5.Theme parks

10. Advantages
• GRC was developed as a corrosion free alternativeto traditional steel
reinforced concrete.
• GRC can be moulded intoany complex shape,profiles and
architectural components.
• Main advantage over precast concrete is one can have very light
structures resultingin savings in thecosts of transportation,handling
and erection of panels.
• Lightweightdesign(both low and highrise superstructures) helps
both in economicsavings and also effectthe sustainable
environment.
• GRC is durable,seismic capable,chemical resistant,non combustible
and good sound and heat insulator.

13. 4.Nanomaterials
• Nanotechnology:When combined with ultra-high-strength
concrete, nanomaterialssuch as Carbon Nanotubes(CNT’s)
create a materialso strong in both tensionand compression
thatsteelreber is no longer needed in construction.

Mega-city pyramid concept
Tokyo was so large that it
could be only completed
with kelp of carbon
nanotubes.

14. 5.Self healing concrete
• Thegreat downfallofconcrete-the
worldsmostwidelyusedmaterial
is–unavoidablecracking,caused
bywater andchemicals.
• Buta selfhealingconcrete was
developedbyNetherland.Which

15. 6.Germ repellent
• Stopping the spread of disease in a confined space such as hospital is not a easy
task,involving continuous disinfecting.But a team from Harvard produced
“slippery liquidporous surface”(SLIP),that would let bacteria slip off.
• Apart from hospitality application it canward off dust,ice and also graffiti.

16. 7.Sweating rooftops
• Though the idea of a “sweaty”
building sounds rather unpleasant
andawkward.But this new material
from ZTH-Zurichthat aims the
rooftop material toabsorb water
when it rainsand only releases it
when the heat is raised to a certain
temperature.The resulting
evaporation will in turn keep the
house cool-much like the process of
human sweat.
