In 1853, Coignet built the first iron reinforced concrete structure, a four-story house at 72 rue Charles Michels in the suburbs of Paris. [4] Coignet's descriptions of reinforcing concrete suggests that he did not do it for means of adding strength to the concrete but for keeping walls in monolithic construction from overturning. [ 5 ]
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 ...
In order to strengthen the concrete containers, he experimented with embedded iron mesh. He was not the first to experiment with reinforced concrete, but he saw some of the possibilities in the technique, and promoted it extensively. Monier exhibited his invention at the Paris Exposition of 1867. He obtained his first patent on 16 July 1867, on ...
In 1884 after experimenting with reinforced concrete sidewalks, he patented (U.S. patent 305,226) a system of ferro-concrete with the iron rods twisted to improve the bond, then developed a patented Ransome system for practical reinforced concrete construction. In 1886 Ransome built two small underpass bridges in the Golden Gate Park in San ...
Rebar (short for reinforcing bar), known when massed as reinforcing steel or steel reinforcement, [1] is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension.
The durability design of reinforced concrete structures has been recently introduced in national and international regulations. It is required that structures are designed to preserve their characteristics during the service life, avoiding premature failure and the need of extraordinary maintenance and restoration works.
Reinforced concrete is concrete in which steel reinforcement bars ("rebars"), plates or fibers have been incorporated to strengthen a material that would otherwise be brittle. In industrialised countries, nearly all concrete used in construction is reinforced concrete.
François Hennebique (26 April 1842 – 7 March 1921) was a French engineer and self-educated builder who patented his pioneering reinforced-concrete construction system in 1892, integrating separate elements of construction, such as the column and the beam, into a single monolithic element.
