Ferrocement Shell Roof Construction

The are constructed on there sides on the ground and the curve shapes are checked for accuracy using a stake for the center.

Ferrocement shell roof construction.

Ferrocement tanks are used in many regions of the world as water storage tanks. Half circle parabolic stress skin roof panels are being lifted into place. Construction around the world. It can be used in combination with plain cement concrete or reinforced cement concrete.

Compared to traditional construction the cement is reinforced with more steel or fiber at a closer spacing. Ferrocement or ferro cement is a system of construction using reinforced mortar or plaster lime or cement sand and water applied over an armature of metal mesh woven expanded metal or metal fibers and closely spaced thin steel rods such as rebar the metal commonly used is iron or some type of steel. Ferro cement being a thin material single piece panel of size. And when used.

The cement is typically a very rich mix of cement and sand in a 3 1 ratio. Reduced spacing yields uniform force dispersion and increases strength. It can be used to form relatively thin compound curved sheets to make hulls for boats shell roofs water tanks etc. For industrially developed countries ferrocement seems economical for medium size storage tanks some type of roof shell construction boats and ships and wherever the ease of forming complicated shapes and the lighter weight of ferrocement can be safely exploited.

There are many structures built of ferrocement housing units shell roofs water tanks and swimming pools biogas digesters silos food storage units and for some specialized applications such as floating marine structures for which reinforced concrete is too heavy. Ferrocement is normally applied to a mixture of portland cement and sand applied over layers of woven or expanded steel mesh and closely spaced small diameter steel rods rebar. Before building the walls and roof of the tank there must be a sturdy foundation in place. Some important uses of ferrocement are as follows.

Ferro cement planks panels can be used for construction of beams columns floor roofs walls chajjas and lintels. Ferrocement channel roof provides light weight roofing 60 reduction in dead weight as compare to rcc pre casting of roof leads to substantial reduction in construction time 20 saving in cost possible because of reduction in steel quantity and elimination of coarse aggregates and.
