Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling. this change, in general, it was proposed to categorize CRR according to corrosion resistance rather than steel type. The levels and steels associated with each level are as follows. • Level 1: Improved Corrosion Resistance Bars: MMFX 2, 2101 LDX (S32101) • Level 2: Moderate Corrosion Resistance Bars: Stainless Steel Clad, 2304 (S32304)inhibitors, and coated reinforcing steel is significantly reducing the occurren ce of reinforcing steel corrosion in new bridges.
