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.)
An axe made of iron, dating from the Swedish Iron Age The earliest iron objects found in Europe date from the 3rd millennium BC, and are assigned to the Yamnaya culture and Catacomb culture .

In the heart of Asia, deep underground, two huge tectonic plates are crashing into each other — a violent but slow-motion bout of geological bumper cars that over time has sculpted the soaring ...
The operation launched a ferro-cement boat on the Hudson River in December 1971 and piloted it to an area near the Bahamas. Upon reaching its destination, it sank in a hurricane. [2] After a number of subsequent failed attempts to construct a habitable sea platform and achieve sovereign status, the project was abandoned.
The iron cycle is an important component of the terrestrial ecosystems. The ferrous form of iron, Fe 2+, is dominant in the Earth's mantle, core, or deep crust. The ferric form, Fe 3+, is more stable in the presence of oxygen gas. [22] Dust is a key component in the Earth's iron cycle.
