Abstract: Electrical measurements are becoming a popular method to examine transport properties of
concrete due to their ability to be performed rapidly and their ease of use. Previous work has
shown that specimen geometry, temperature, and storage conditions influence electrical
readings. As such, caution must be taken when correlating such readings with transport
properties. It is important to correct these factors so that measurements more accurately
describe the material. The work presented in this paper looks specifically at the role
temperature of the specimen play in resistivity measurements. This is done by cycling
samples through a temperature range and developing corrections characterizing their
behavior. A normalized formation factor is proposed to describe transport through the
microstructure. This allows for the determination of a transport property that can be used for
service life prediction. The work is currently being developed as a part of a nation-wide
project aimed at investigating the possibility of moving towards performance based
specifications.
