Description
A Concrete mixture strengthened by the incorporation of a support matrix such as steel bars. Reinforced concrete was patented in 1867 by Joseph Monier, a French gardener who used prepared flower pots and tubs using a thin layer of concrete reinforced with Wire mesh. However, it was not generally used in the U.S. until the 1890s when Ernest Ransome promoted construction methods using reinforcing rods in girders, beams, and floor slabs in conjunction with concrete columns. This method allowed warehouses and factories to be built with more windows. By the 1920s, reinforced concrete was widely for buildings, bridges, dams, roads, sculptures and monuments. The encased Steel can corrode when the alkaline cement fails to provide passivation. This can occur when chloride ions from Sea water, deicing salts, or Calcium chloride accelerators are present. Also, Acid rain and sulfate can erode and crack the alkaline cement opening paths for moisture to corrode the metal and spall the surface through freeze-thaw action.
