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.)
Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand and/or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water. When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid shape.

Family Dollar Stores recalled about 67,000 remote-controlled toy tanks after getting five reports of the controllers overheating and melting, the U.S. Consumer Product Safety Commission said. So ...
An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...
Tanks built below ground level are sometimes used and referred to as underground storage tanks (USTs). Reservoirs can be covered, in which case they may be called covered or underground storage tanks or reservoirs. Covered water tanks are common in urban areas. Tanks can be mounted on a lorry or an articulated lorry trailer.
Although many were small, a tank at Bougival (1872) with a domical roof had a volume of 130 cubic metres. Two tanks of 1000 cubic metres each were built at what is now Bruyères à Sèvres. The two-storey reservoir at Pessac has a 10 cubic metre tank perched above a 20 cubic metre tank, the supporting columns being in the form of tree trunks.
