Corrosion Activity on CFRP-Strengthened RC Piles of High-Pile Wharf in a Simulated Marine Environment

Table 1

Test program.

Specimen groups	Corrosion degree (% steel mass loss)
	0	5%	10%	15%	20%
Poststrengthened	—	—	CF5-10	CF5-15	CF5-20
Strengthened	—	CF5	CF10	CF15	CF20
Unstrengthened	N0	N5	N10	N15	N20

Notes. CF5-10 denotes that a pile specimen firstly corroded to 5% steel mass loss, then was strengthened by CFRP, and corroded to 10% steel mass loss. N10 denotes an unstrengthened pile specimen that was subjected to 10% steel mass loss.
