context_page_description: Ferrocement or ferro-cement is a system of construction using reinforced mortar or plaster 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. The cement is typically a very rich mix of cement and sand in a 3:1 ratio; and when used for building boats no gravel is used, so that the material is not concrete.
  Ferrocement is used to construct relatively thin, hard, strong surfaces and structures in many shapes such as hulls for boats, shell roofs, and water tanks. Ferrocement originated in the 1840s in France and the Netherlands and is the origin of reinforced concrete. It has a wide range of other uses including sculpture and prefabricated building components. The term "ferrocement" has been applied by extension to other composite materials, including some containing no cement and no ferrous material.
  The "Mulberry harbours" used in the D-Day landings were made of ferrocement, and their remains may still be seen at resorts like Arromanches.

  Ferro Cement is made with wire mesh of diameter 0.5mm to 1 mm reinforced between cement mortar of ratio 3:1 of cement and sand.
