Reinforced concrete invention

Concrete is concrete meaning. Reinforced concrete is reinforced concrete, is widely used in building construction. Before pouring the concrete, the first for formwork tie bars, which is reinforced with wire fixed to the structure of the desired shape, then cover with a template outside steel skeleton. Finally, the concrete pouring in, after curing to achieve the standard form removal strength, that is, the resulting reinforced concrete.

Invention of reinforced concrete appeared in modern times, people generally think invented in 1848. In 1868 a French gardener, including access to the reinforced concrete flower pots, used in highway guardrail and followed by reinforced concrete beams patent. In 1872, the world's first reinforced concrete structure of the building was completed seat in New York, the history of human building a new era began, reinforced concrete structure in 1900 after the engineering side has been large-scale use. In 1928, a new form of reinforced concrete structures prestressed concrete appeared, and was also widely used in engineering practice after World War II. Invention of reinforced concrete and steel used in the mid-19th century, the construction industry to make the construction of high-rise buildings and long-span bridges as possible.

Reinforced concrete is today one of the leading building material, but it is neither the inventor engineer nor building materials specialist, but a French gardener. He has a big garden, open all year round beautiful flowers, but the flower beds are often Tasui tourists. To this end, Moni Ai often think: "Is there any way that people can not only set foot flower beds, not easy to crush it?" One day, when Moni Ai transplanting flowers, accidentally broke a potted plant, flower pots smashed to pieces, flower soil around the root ball but only package. "Oh! Flowers and roots crisscross the loose soil firmly linked together!" He inspired from this incident, modeled on the wire mesh woven flowers and roots, and then cement, sand and gravel were stirred together made flower beds, very strong indeed.
