I am a final B.tech Civil Student. As part of my course I wish to do seminar on "Emergency Shelter through Super Adobe Technology". I wish I could get a detailed Seminar report on this topic with abstract, objectives,introduction,references, journals,conclusions etc. It is to be submitted before 24th July,2013. Please reply.

Hai,
pls go through this information about Superadobe,it is a form of earthbag construction that was developed by Iranian architect Nader Khalili. The technique uses layered long fabric tubes or bags filled with adobe to form a compression structure. The resulting beehive shaped structures employs arches, domes, and vaults to create single and double-curved shells that are strong and aesthetically pleasing. It has received growing interest for the past two decades in the Natural building and Sustainability movements.
On-site earth – optionally mixed with stabilizing material (e.g. lime or cement) – is filled into polypropylene bags (sandbags) or tubes (the uncut raw material of the bags). Next the superadobe tube is tamped like it is done when we build a traditional rammed earth house.We lay strands of galvanized barbed wire between the superadobe rows, which keep the layers together (like mortar) and increase the tensile strength of the structure.
The long-lasting polypropylene (PP) tube acts as a formwork that stays is the wall giving a permanent extra strength to the structure. The water can leave the earth trough the gaps of the woven strands of the PP tube, and it keeps the filled plastic earth together until it gets dried and set. Finally the wall is plastered that protects the PP from the damage that UV-radiation could cause to it.
Superadobe is like a large “superlong” adobe, an instant and flexible wall generator, which we can use to form long rows without intermission.Since the raw earth is plastic and the tubes are flexible, we can easily build a great variety of structures, not only squared buildings but also arched walls, vaults and domes that have many static and aesthetic advantages.
Building with Superadobe is easy, environmentally and economically friendly, and anyone can learn it.
Superadobe structures are stable and water resistant, and can resist even to extreme weather and environmental conditions – like floods, windstorms, fire or earthquakes.
