FERROCEMENT Sakhali type Bandhara CAN DO MAGIC. This is a material of next millennium
Introduction • 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

Sakhali type Bandhara Objects To store rain water To recharge ground water To stop erosion of nalla To increase retention time of water in villages. NALLA
NALLA Sakhali type Bandhara
NALLA FLOW Sakhali type CURVED Bandhara
1 m to 2 m Ferrocement with Double chicken mesh Steel bars skeleton Then Mortar to be pressed In the gap. Thickness 40 to 50 mm Sakhali type Bandhara
Ferrocement Anchors in the sides of nalla 1 meter Bandhara is stable as there no tensions zone in the wall due to curvature Sakhali type Bandhara
Cross section Of ferrocement curved bandhara Filling by available boulders In nalla Sakhali type Bandhara
Cross section Of ferrocement curved bandhara Local soil or sand Filling between two walls Filling by available boulders In nalla Sakhali type Bandhara For height 2 to 2. 5 meter
Advantages 1. 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 meshes 5. On both sides of the curved ferrocement wall We 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. For more information visit www. ferrocementindia. com Email ferrocement@gmail. com
