Reinforced Concrete
Reinforced concrete embeds steel bars or mesh in concrete, combining concrete's compressive strength with steel's tensile strength. It became the dominant material for modern buildings and infrastructure.
Attribution — Built up over time by many contributors, often across different regions.
Joseph Monier patented iron-reinforced concrete for tubs and tanks (from 1867), but reinforced concrete as a structural system was developed cumulatively — William Wilkinson, François Hennebique, and Ernest Ransome each advanced it independently.
What counts as the invention: Early reinforced objects (Monier) differ from the structural design systems (Hennebique, Ransome) that made buildings possible.
