Potentiodynamic polarization parameters for the corrosion of rebar embedded in OPC, PPC, and PSC M40 grade concrete (90-day cured specimens).

System	Various grades of concrete
	M30			M40
	(mV versus SCE)	(mA⋅cm^−2) × 10^−4	Corrosion rate (mmpy) × 10^−3	(mV versus SCE)	(mA⋅cm^−2) × 10^−5	Corrosion rate (mmpy) × 10^−4
OPC	−397	6.9922	8.0082	−301	2.1496	2.491
PPC	−303	1.6902	1.9589	−263	1.6902	1.9589
