	Ferrocement - Wikipedia, the free encyclopedia
		Ferrocement is both a method and material used in building or sculpture with cement, sand, water and wire or mesh material - often called thin shell.
		Thin shell ferrocement offers strength and economy along with broad application to include home building, creating sculptures, or building boats and ships.
		In the yacht world, many designers, mostly in the 1970's, adapted their designs to the then very popular backyard building scheme of building a boat in the ferrocement medium.

	Ferro cement
		Although ferrocement is not strictly a 'sustainable' technology as it uses cement and steel, it nevertheless employs them in a highly efficient and cost-effective manner.
		Ferrocement in Auroville is used, among other things, in the construction of roof channels, doors, water tanks, latrines, slabs, various form works and biogas plants.
		Ferrocement is a form of reinforced concrete using closely spaced multiple layers of mesh and/or small diameter rods completely infiltrated with, or encapsulated in, mortar.

	Cement Association of Canada - Ferrocement
		Ferrocement is a special type of reinforced concrete composed of closely spaced layers of continuous relatively thin metallic or nonmetallic mesh or wire embedded in cement-sand mortar.
		Ferrocement is considered easy to produce in a variety of shapes and sizes; however, it is labor intensive.
		Ferrocement is used to construct shell roofs, swimming pools, tunnel linings, silos, tanks, prefabricated houses, barges, boats, sculptures, and thin panels or sections usually less than 25 mm thick (ACI 549R and ACI 549.1R).

	Hvad er ferrocement til bådbygning
		Stems, keels, sterns, frames etc. are set up for a ferrocement boat in exactly the same way as for any other type of boat building and the stringers and external wire netting goes on in exactly the same way as for a conventional timber planked boat, or a steel or ply-wood vessel.
		Ferrocement is really a "hybrid" reinforced concrete, differing in the fact that the steel reinforcement matrix predominates rather than the concrete (mortar).
		Many of the fine examples of ferrocement construction available today were built by professionals, or by amateurs with professional help, or by amateurs with a truly professional and time consuming approach to the construction.

	The Tribune, Chandigarh, India - Science Tribune
		Ferrocement is a composite material in which the inherent properties of two constituent materials are best made use of.
		Ferrocement encased structural members not only impart strength to the members, but for equal strength it helps in reducing the cross sectional area of the member, thereby reducing the dead load of the structure or its member.
		The ferrocement encased building or structure will bend or distort and this excessive bending or distortion could be remedied after the tremors are over.

	9. REQUIREMENTS SPECIFIC TO FERROCEMENT BOAT CONSTRUCTION AND FERROCEMENT/TIMBER FITTING OUT
		Ferrocement engine beds are the means not only of attaching and aligning an engine accurately, but also a means of giving considerable additional longitudinal strength to the hull.
		If ferrocement is used, access to the bilges and shaft must be given due thought, as well as the means to get at the hull and deck in the event of sustaining any damage in the fish hold area.
		The ferrocement lining can be constructed by leaving 6 mm rod ties protruding from the hull and deck, gluing the insulation into position and finishing with two layers of mesh on a layer of 6 mm rods.

	Cranfield University, DCMT - Ferrocement as permanent formwork to reinforced concrete (Site not responding. Last check: 2007-10-12)
		Ferrocement is a structural material comprising a cement mortar matrix highly reinforced with layers of small diameter wire mesh uniformly distributed throughout a relatively thin cross-section.
		As distinct from conventional reinforced concrete it tends to behave as a homogenous material with greatly improved tensile characteristics.
		In this programme of research an increase in strength of 15% over conventional reinforced concrete was achieved by the use of permanent ferrocement formwork.

	Analysis and Behavior of Ferrocement in Flexure (Site not responding. Last check: 2007-10-12)
		Concurrently, an analytical model was developed to generate the nonlinear moment-curvature and load-deflection curves of ferrocement beams from the measured stress-strain curves for mortar in compression (including the descending portion) and steel meshes in tension.
		The model is shown to satisfactorily predict the load-deflection curves of ferrocement as well as those of reinforced concrete beams.
		A simple upper bound relationship is proposed to predict the average crack width in ferrocement for a given strain or stress in the extreme layer of steel mesh.
