The history of concrete

The history of concrete

  In 1990, the Universal Exhibition demonstrated the use of reinforced concrete in many ways, causing a revolution in the field of building materials. After seeing Monnier's planters, canopies and water tanks made of wire mesh and concrete at the Paris Exposition in 1867, the French engineer Einaric was inspired and the bathrooms managed to use this material for house construction. 

  In 1879, he started manufacturing reinforced concrete floor slabs, which later developed into complete buildings using structural concrete beams reinforced by steel hoops and longitudinal rods. In recent years, when she built apartment buildings in Paris, the use of reinforced concrete main columns, beams and floor slabs that have been modified to date are still commonly used, 1884 you that the German construction company purchased Monier's patent, conducted the first scientific experiments on reinforced concrete, the study of the strength of reinforced concrete, fire resistance. The bond between steel and concrete. 

  1887 German engineer Kollen restricted published the calculation of reinforced concrete; the British Wilson applied for a patent for reinforced concrete slabs; the American Hayter conducted tests on concrete beams. 1895 - 1900, the first bridges and sidewalks were built in France reinforced concrete. 1918 Abrams published the noted calculation of the strength of concrete water-cement ratio theory. Reinforced concrete started to become an important material that changed the landscape of this world.
