The First Reinforced-Concrete Skyscraper
The history of reinforced-concrete construction is sometimes re-garded as originating in the seventeenth-century invention of strength-ening masonry by the introduction of iron tie rods and armatures into the body of the masonry work.' The essential factors in the progress of the art, however, are the revival of concrete as a structural material

Concrete that includes embedded metal (usually steel) is called reinforced concrete or ferroconcrete. Iron reinforced concrete was invented (1849) by Joseph Monier, who received a patent in 1867. Joseph Monier was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh. Reinforced concrete combines the tensile ...

Reinforced concrete Although concrete is strong in compression (able to carry heavy weights), its tension performance is poor (when under a bending load). The solution was found in the early 1800s, when wrought iron bars, and later cast iron I-beams, were embedded in the concrete. Although various British, American

The use of reinforced concrete in the United States dates from 1860, when S.T. Fowler obtained a patent for a reinforced concrete wall. In the early 1870s, William E. Ward built his own house in Port Chester, New York, using concrete reinforced with iron rods for all structural elements. Despite these developments, such construction

1889 The first concrete reinforced bridge is built. 1890 The addition of gypsum when grinding clinker to act as a retardant to the setting of concrete was introduced in the USA. Vertical shaft kilns were replaced with rotary kilns and ball mills were used for grinding cement. 1891 George Bartholomew placed the first concrete street in the USA in

The Concrete Reinforcing Steel Institute is proud to honor five great concrete bridges built between 1990 and 2000. Each stands as a solid testament to concrete’s versatility, its cost effectiveness, and its durability. From arches to swing leaves, from foundation to superstructure, concrete is clearly a superior bridge-building material.
