electrochemical chloride extraction on small cement objects?

[shammypenny2]

Hi all,
I would like to ask if electrochemical chloride extraction method can be performed on a panel sizes of 180mm x 100mm
and 5 meter long made with steel reinforced cement.
Would the cost be high performing ECE?
what type of equiments required?
please advise, thank you all.

I would suggest an investigation and options study by a suitably experienced consultant.

The feasibility of chloride extraction as a reinforcement corrosion prevention depends on the extent of chloride penetration beyond the steel, amongst other things.

If it is a technically appropriate option then the decision would be based on cost of the repair vs. cost to demolish and replace the element. Cost of chloride extraction is usually a little less than cathodic protection and does not require ongoing monitoring and maintenance, however it is usually more than basic patch repair and coating.

What are the chloride profiles like, the cover depth, the extent of any delamination or spalling, etc. etc. ? How many square metres in total are you looking at remediating and in what configuration? There are many questions.
