Mechanical Performance versus Corrosion Damage Indicators for Corroded Steel Reinforcing Bars

Table 8

Relation of CDI and PIs for practical corrosion conditions.

CDI	Nominal diameter: 16 mm
Corrosion rate [µm/year]	Time in years to reach a mass loss of 5% for the following conditions
	Poor concrete, low concrete cover, and/or cracked concrete		Uncracked concrete or only small cracks together with a good concrete and a sufficient concrete cover
Low: 1.16	>150		>150
High: 11.6	<20		<45
PIs	Nominal diameter: 16 mm
Mass loss [%]	Mean value; res. [—]	5% quantile value res. [—]	Mean value; res.dE [%]	5% quantile value res.dE [MPa]
5.0	0.8	0.55	80%	55%
Mass loss [%]	Mean value res. [%]		5% quantile value res. [%]
5.0	50		25
