[Metropolia Student Project Seminar 24.5.] Innovative Building Materials
- 1. Innovative Building Materials: A Report on Oriented Strand Board, Plywood & Similars, CO2 Absorbing Concrete, and Reactive Powder Concrete Mikhail Shandalovich Zachary Hawkins Deniz Löktas Peteris Putelis
- 2. Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
- 3. A sustainable material meets the needs of this generation, without compromising the ability of the next generation to repurpose or recycle that material to meet their own needs. Does your material cost less to produce than standard materails? Yes NO Does your material perfom on a scale that is Does your material out perform existing better than its percentage of existing materials marterials on a scale equal to its cost cost increase? Yes No Yes No
- 4. Innovative Materials Oriented Strand Board Plywood and it’s Simalars CO2 Absorbing Concrete Reactive Powder Concrete
- 6. Oriented Strand Board OSB is an engineered wood product formed by layering strands (chips) of wood in specific orientations. Created in Canada in the late 1970s, OSB is a result of waffle board development. http://image.made-in-china.com/2f0j00HBvQptWavMzj/OSB- Board-1.jpg
- 7. Production Layers are laid down sequentially: longitudinal, transverse and longitudinal. Adhesive resin is sprayed with a rotating disks. http://www.cambridge-biopolymers.com/images/OSB%20and%20resin.jpg http://upload.wikimedia.org/wikipedia/commons/7/71/OSB_production.jpg
- 8. Classification: - OSB1 - OSB2 - OSB3 - OSB4 Materials: - Pine wood (originally) - White birch - Maple - Amber wood - Rubber tree - Eucalyptus http://i00.i.aliimg.com/img/pb/805/275/245/1272427387103_hz_fileserver3_1952093
- 9. Implementation Why to use OSB in construction? - No shrinkage - No design restrictions - Lower price - Expedited construction Sustainability OSB recycles wooden production waste material: chips and other wooden particles.
- 11. PLYWOOD and similars Plywood is a wood product which is made of layers parallel to each other with 0 or 90 degrees angle. It is possible to be covered by any other material. Photos by Deniz Löktas 2012
- 12. Any thickness and extra material layer. Any color is possible. Photos by Deniz Löktas 2012
- 13. Interviews Lars Ostenfeld Eric Pollock - Jouni Kalliomäki Riemann - METROPOLIA - METROPOLIA RAMBOLL Photos by Deniz Löktas 2012
- 14. Innovation Wood materials have been started to be considered as materials to make buildings with seismic strength. For this purpose, a 7 storey wooden building was tested in Japan against earthquake, in 2007 by Italian Professor Ario Ceccotti, University of Venice, Civil Engineering Department. There are similar researches made in USA by National Science Foundation, under the name Prof. Ario Ceccotti of NEESWood Project. www.dolomitipro.it/foto/anteprima/prof_ario_ceccotti_cnrivalsa,17.jpg
