The Performance of Carbon Fibre Composites as ICCP Anodes for Reinforced Concrete Structures

Table 1

Test programme of carbon fibre anode in saturated Ca(OH)₂ and concrete electrolyte.

Specimen	Electrolyte	ID	Total surface area (cm^2)	Voltage applied (V)
1.1	Ca(OH)2	Steel 1	37.7	10
		CFRP rod 1	37.7
1.2	Ca(OH)2	Steel 2	37.7	10
		CFRP fabric 2	400k^∗
2.1	Ca(OH)2	Steel 3	37.7	20
		CFRP rod 3	37.7
2.2	Ca(OH)2	Steel 4	37.7	5
		CFRP fabric 4	487.5k^∗
3.1	Concrete	Steel 5	43.96	10
		CFRP rod 5	43.96
3.2	Concrete	Steel 6	43.96	10
		CFRP fabric 6	840k^∗

^∗k is a constant that takes account of the difference between the real and apparent surface area of the CFRP fabric (see Section 3.2).
