What is reinforced concrete? How to use in English

The term "reinforced concrete" describes a building material that has a special feature: strengthening reinforcement bars (rebar) are added to concrete before it hardens. This helps to make the material stronger and more durable than regular concrete, as the concrete's inherent weaknesses - such as brittleness and susceptibility to cracking under compression - are counteracted by the reinforcement bars. The idea of reinforcing concrete with steel dates back to the late 19th century, when several engineers experimented with adding reinforcement to concrete structures. In 1889, an Englishman named Joseph Monier received a patent for an improved version of a concrete pipe that utilized steel reinforcement. The term "reinforced concrete" was coined by an Austrian engineer named Friedrich Josef Joseföffy in 1892, as he wrote about this new material in an engineering journal. Reinforced concrete gained popularity in the early 20th century, due in part to the work of French engineer François Coignet. He developed a method of instruction utilizing a system of mathematical calculations and graphical illustrations, making it easier for architects and engineers to design structures using reinforced concrete. Reinforced concrete quickly became a go-to material for many large-scale construction projects in the years that followed.
