Assessment of structure formation in fresh concrete by measurement of its electrical resistance

Investigation reports on accelerated curing of concrete using direct electrical conduction with a view to minimizing the temperature rise and so improving durability and reducing energy costs. There are doubts regarding the long term durability of concrete produced using accelerated curing methods. The authors investigated the process and concluded that corrected resistance may be a suitable measure of structure formation in concrete for investigation of accelerated curing, whilst comparison between the corrected resistance of an accelerated sample and a reference sample will allow calculation of the structural gain in hours for the temperature cycle considered.
