The emergence of high-rise buildings is inseparable from the invention of reinforced concrete
Reinforced concrete (English: Reinforced Concrete or Ferroconcrete) is often referred to as reinforced concrete (tong) in engineering. It refers to a composite material that works together to improve the mechanical properties of concrete by adding steel mesh, steel plates or fibers to concrete. The most common form of reinforced concrete.
The invention of reinforced concrete appeared in modern times. It is generally believed that the French gardener Joseph Monier (en: Joseph Monier (English)) invented reinforced concrete in 1849 and obtained the invention in 1867, including reinforced concrete flower pots and This was followed by a patent for reinforced concrete beams and columns used in highway guardrails. In 1872, the world's first reinforced concrete structure building was completed in New York, USA. A new era in the history of human architecture began. Reinforced concrete structures were used on a large scale in the engineering field after 1900. In 1928, a new type of reinforced concrete structure, prestressed reinforced concrete, appeared and was widely used in engineering practice after World War II. The invention of reinforced concrete and the use of steel in construction in the mid-19th century made it possible to construct high-rise buildings and long-span bridges.
Currently in China, reinforced concrete is the most widely used structural form, accounting for the vast majority of the total. At the same time, China is also the region that uses the most reinforced concrete structures in the world. The output of cement, its main raw material, reached 1.882 billion tons in 2010, accounting for about 70% of the world's total output.
