New materials used in building industry

  1. 1. New Materials Presentedby:
  2. 2. Why choose a right material??? • Ecological balance • Green building material • Economical structures • Faster construction • Aesthetic advantages
  3. 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. 4. • TheseETFEsheetsare transparent likeglassandtrasmitmore light thanglass. • Cost24%to70%lessthanglassto install. • ETFEsheetsare chemicallyinert,so theydontdegradeunderUVrays. • Asithastefloninit.Itis nonsticky,soitkeepsitselfclean. • Recyclable:Attheendoftheuseful lifeofatleast50yrsto200yrsitcan bemeltedandreused...
  5. 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. 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. 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. 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. 9. • Applications 1.Architectural cladding 2.Architectural moulding 3.Building components 4.Industrial products 5.Theme parks
  10. 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.
  11. 11. GRCpanels
  12. 12. 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. Tje Shimizu TRY 2004 Mega-city pyramid concept Tokyo was so large that it could be only completed with kelp of carbon nanotubes.
  13. 13. 5.Self healing concrete • Thegreat downfallofconcrete-the worldsmostwidelyusedmaterial is–unavoidablecracking,caused bywater andchemicals. • Buta selfhealingconcrete was developedbyNetherland.Which saysbyinfusingbacterialsporesin concretehelpinpatchingup crackswhenwater seepsthrough. La Tourette
  14. 14. 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.
  15. 15. 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.
