Design and Construction of Folded Ferrocement Boat

Abstract

The purpose of this paper is to explore the technique of Design And Construction Of Folded Ferrocement Boat building for sustainable housing. Ferrocement involves the use of conventional cement with fine aggregate and several layers of steel, with the advantage of greater strength than conventional reinforced concrete, limited formwork and thinner sections. It is particularly suitable for thin shell structures, where bending loads are minimized by geometry.

Historical and present applications of Ferrocement are covered, along with other building techniques, in order to establish best practices and possible improvements. A particular focus is on reducing construction work, which in recent years has limited ferrocement development.

Computer modeling of shell form finding is described, with three case studies being created. A structural analysis method to verify general building code security is described and applied to each case study.

Conclusion

Ferrocement construction is an exciting alternative to conventional methods of wood and masonry. Aspects such as strength, durability, architectural freedom, occupant comfort, affordability and energy efficiency align well with the qualities of ferrocement in the context of sustainable housing. This project explores its rich types of history and structure, including water tanks, houses, boats and large public spaces.

Inflated fabric, spray foam isolation, and laminated ferrocement technique can drastically reduce armature work. Using flexible non-metallic materials such as basalt increases durability and makes the mesh easier to handle and shape. With fly ash, mortar composition can be improved for faster shotcrete application.

Energy efficiency is verified with DesignBuilder energy modeling. Many ideas are borrowed from the strict specification of PassivHaus, including the use of heat pumps, heat recovery, thick insulation, energy-efficient lighting and appliances, as well as window shading. Each case study can meet specific energy demand limits for heating and cooling in PassivHaus. Recommendations for on-site solar PV system size would enable houses to achieve annual net zero use of electricity.
