TOWARDS A FIRE STABILIZED BUILDING TECHNOLOGY: TOWARDS A FIRE STABILIZED BUILDING TECHNOLOGY Instructor: Dr. Charles Graham Ph.D. AIA Prepared By: Suhag Kansara
MUD: MUD CEMENT “SHIFT OF PARADIGM”
New products: New products Urbanization Techniques for Construction Soaring Costs Sky high competition Rural Housing Housing issues Neglected Housing issues Half-baked Cost Effective Solution Best Use of Locally Available Materials
Building the Vault in Nubian Way: A House in Auroville Rural Housing Building the Vault in Nubian Way Green Bricks drying in the mud Burning the Kiln Finished with laterite earth, lime and cement
Slide5: Effective Cost Cycle Approximate Cost of the House
Rs. 978 – 1086/-
$19-$22 per sq. m. Cost of R&D
Rs. 3,000
$60 Hence, Total Cost of the House
Rs. 65,000/-
$1,300 Return of Product Sales
(Sales of Bricks)
Rs. 45,000/-
$900 The Actual Price
Rs. 369/-
$8 per sq. m.
Slide6: A problem of Scale / Factors in Cost Large Scale Production System for more efficiency
Government help – subsidized loans
Mud buildings are vulnerable to unseasonable rains when a large quantity of mud products has to be protected
Invalidation of Process Foundation cost is high and the vaults fairly high
Most of the work is unskilled i.e. moving bricks, loading – unloading, adding cow dung/rice husks, clay over the vaults
Due to its porosity exterior walls should be plastered with cement or lime based mixture
Floors can be filled with fired product, interiors walls can be plastered according to budget
Slide7: Conclusion / Materials for Future An Appropriate cost & energy efficient technology that has a great future.
Contributing to sustainable development
Uses semi-skilled manpower
Technology is easily adaptable and transferable
The energy and monetary costs are much lower
The vibratory atmosphere are very positive
Variations of soil quality and hence blocks quality may suffer
Soil with poor characteristics can cause shrinkages and cracks
Mud buildings are vulnerable to unseasonable rains when a large quantity of mud products has to be protected
Slide8: Finding connectivity A connection to Builder’s Yard ????
Nucleus of entirely different and more personal relationship between builder and community.
In the case of Auroville, builder and community is same – self dependency for housing construction
Very organic in nature
Slide9: Thank You
