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.)
Joseph-Louis Lambot (born 22 May 1814 in Montfort sur Argens; died 2 August 1887 in Brignoles), is the inventor of ferro-cement, which led to the development of what is now known as reinforced concrete. He studied in Paris, where his uncle Baron Lambot was aide-de-camp to the Duke of Bourbon.
A short video of the last beam being placed on a raised road, part of a new road near Cardiff Bay, Wales. A beam bends under bending moment, resulting in a small curvature. At the outer face (tensile face) of the curvature the concrete experiences tensile stress, while at the inner face (compressive face) it experiences compressive stress.
Steel shortages during World War I led the US to build experimental concrete ships, the largest of which was the SS Selma, today partially submerged in Galveston Bay and visible from both the Houston Ship Channel and Seawolf Park. SS Selma was built in Mobile, Alabama, and named to honor Selma, Alabama, for its successful wartime liberty loan ...
Video from a doorbell camera at a home on Prince Edward Island, Canada, has surfaced that showed a rock hurtling from the sky and crashing into a patio with a loud crack.

Ferropericlase or magnesiowüstite is a magnesium/iron oxide with the chemical formula (Mg,Fe)O that is interpreted to be one of the main constituents of the Earth's lower mantle together with the silicate perovskite ((Mg,Fe)SiO 3), a magnesium/iron silicate with a perovskite structure. Ferropericlase has been found as inclusions in a few ...
