Steel corrosion is the most common degradation of reinforced concrete structures. Corrosion weakens the steel reinforced structure and may reduce the structural factor of safety to below the design value. Strengthening/repair work is then required. The NAMI developed green and nano-modified fabric reinforced cementitious matrix (FRCM) offers excellent fire resistance, mechanical properties and durability. It is adopted for strengthening and repairing the structures with corroded steel.
