FERROCEMENT
Sakhali type Bandhara
CAN DO MAGIC.
This is a material of next millennium
• Ferrocement, a versatile material, involves thin construction elements ranging from 20-25 mm. thickness using layers of continuous /small diameter steel wire meshes, impregnated with a very rich cement mortar.
• Ferrocement is the most inexpensive--using few resources, less energy, less polluting, generating less waste and protecting the environment and an attractive alternative construction technique
• Ferrocement elements can resist high impacts or undergo large deformations before cracking or high deflections before collapse
• There has been an increasing activity with ferrocement construction throughout the world including Canada, USA, Australia, China, India, Thailand, Mexico, Indonesia and other developing countries
Introduction
1. Govt is serious about helping villages.2. Govt has issued guidelines and GR3. Govt has alloted funds for Famine.4. ZP and Jalsandharan Department can do
magic in a short time.

Bandhara is stable as there no tensions zone in the wall due to curvature

Local soil or sand Filling between two walls
Advantages1. Fabrication of skeleton and mesh can be done
outside and all the 10 or 15 meshes can be brought to site at a time.
2. Fixing will take one day.3. For mortar we use 1:2 cement mortar.4. Skilled mason will fill the mortar in the meshes5. On both sides of the curved ferrocement wallWe will fill the locally available boulders by hand
packing.6. 12 bandharas can be built in 12 days.7. This can be done up to 2 meter height.For more heights we can have double walls and filled
by soil.
Ferrocement now applied for cavity walls and hollow floors of buildings also.
