... the use of stainless steel ( 2 ) or fiber composite ( 3 , 4 ) reinforcements. At a moderate increase in overall project costs, stainless steel rebar would not be as susceptible to corrosion as mild steel rebar. Polymer and fiber composite reinforcements would eliminate the causes of corrosion problems...
