1 This is a material of next millennium FERROCEMENTSakhali type BandharaCAN DO MAGIC.This is a material of next millennium
2 IntroductionFerrocement, a versatile material, involves thin construction elements ranging from 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 techniqueFerrocement elements can resist high impacts or undergo large deformations before cracking or high deflections before collapseThere has been an increasing activity with ferrocement construction throughout the world including Canada, USA, Australia, China, India, Thailand, Mexico, Indonesia and other developing countries2

12 Sakhali type Bandhara Ferrocement with Double chicken mesh Steel bars skeletonThenMortar to be pressedIn the gap.Thickness 40 to 50 mm1m to 2mSakhali type Bandhara
13 Sakhali type Bandhara Ferrocement Anchors in the sides of nalla 1 meterBandhara is stable as there no tensions zone in the wall due to curvatureSakhali type Bandhara

15 Of ferrocement curved bandhara Cross sectionOf ferrocement curved bandharaLocal soil or sandFilling between two wallsFilling by available bouldersIn nallaSakhali type BandharaFor height 2 to 2.5 meter
16 AdvantagesFabrication 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.
