Use thermography camera to know delaminations

Re: Structural Concrete Flaws Thanks Ranjeet.

Do you mean bonding between steel reinforcement and concrete?

Cheers.

what information are you wanting from your inspection? this will help determine what type of test is best for your application.

Re: Structural Concrete Flaws cracks in reinforced concrete beam...

if possible, loss in prestressing wires.

thanks in advance.

I think there are many other reasons too. Firstly its important to know what member is it---is it under vibrations or in an area where settlement can occur and it has not been taken into design, size etc.
While loss in prestress is cumbersome to measure, in my view if its a beam for example, regular deflection in comparison to actual designed should be made, ckeck for the bearings condition, if the member is too thick, then the temperature difference between the two surfaces. Thus as rightly pointed out through an earlier comment, type of member, and purpose will guide in spotting the cracks and then offcourse the ladder and the magnifying glass tell a lot more.
