What is it about?
This protocol describes the procedure to express fresh pore solution from cementitious systems and the measurement of its ionic composition using X-ray fluorescence. The ionic composition can be used to calculate pore solution electrical resistivity, which can be used, together with concrete electrical resistivity, to determine the formation factor.
Why is it important?
This video article shows how to obtain pore solution from a fresh cement paste for use in determining the formation factor.
