Conductivity of concrete is related to the pore structure and the ions existence in the concrete. Now how can we measure effective conductivity considering the effect of both factors?

Thanks Nirmala for these interesting papers which some of them I came across previously but I am mostly concentrating on ionic systems such as alkali activated cements and will be thankful to have your idea.
Hello Dali,
I dont really have much to comment on this topic but you can use General Electric Model (GEM) for concrete applications of Prof. Zhongjin Li (HKUST) and XY Li's works.
If you are really interested in more info, feel free to contact me for confidential papers.
Cheers
The various methods will still give you the conductivity. You would need to make concretes with different pore structures, and mearure these.
The formation factor is defined in terms of the conductivity of the bulk sample vs. that of the pore solution. You can express pore solution at high pressure and measure its conductivity/composition. Alternately, you can estimate the pore solution conductivity using a calculator available on the web at:
