Ferrocement or ferro-cement [1] is a system of construction using reinforced mortar [2] 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, and the mesh is made with ...
The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. (Ferrocement ships require thick hulls, which results in either a larger cross-sectional area that hurts hydrodynamics, or leaves less space for cargo.)
Before the 1870s, the use of concrete construction, though dating back to the Roman Empire, and having been reintroduced in the early 19th century, was not yet a proven scientific technology. Ernest L. Ransome , an English-born engineer, was an early innovator of reinforced concrete techniques at the end of the 19th century.
More recently the system is being re-launched by Dante Bini's son Nicoló Bini, AIA. Improvements to the original system include greater architectural flexibility, compliance to international building codes, simplification of the construction process and integration of latest material and passive heating/cooling technologies. It is touted as a ...
SS Selma was an oil tanker built in 1919 by F.F. Ley and Company, Mobile, Alabama. President Woodrow Wilson approved the construction of 24 concrete vessels of which only 12 were actually completed.
The first stage saw the use of reinforced concrete slabs by the builder John Young who was Sydney's first protagonist of ferro-cement construction. [ 1 ] Sometime between 1887 and 1894 the Lands Department Datum Bench Mark Plug was set into position on the front of the building and provided the origin of all levels in NSW under the Survey Co ...

By the mid-19th century, some boats had been built with iron or steel frames but still planked in wood. In 1855 ferro-cement boat construction was patented by the French, who coined the name "ferciment". This is a system by which a steel or iron wire framework is built in the shape of a boat's hull and covered over with cement.
