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 ...
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.
When the cement paste is exposed to the air and meteoric water reacts with the atmospheric CO 2, portlandite and the calcium silicate hydrate (CSH) of the hardened cement paste become progressively carbonated and the high pH gradually decreases from 13.5 – 12.5 to 8.5, the pH of water in equilibrium with calcite (calcium carbonate) and the ...

The Indus Valley civilization (3000–1500 BC) made use of granaries and water tanks. Medieval castles needed water tanks for the defenders to withstand a siege. A wooden water tank found at the Año Nuevo State Reserve (California) was restored to functionality after being found completely overgrown with ivy. It had been built in 1884.
