Characterizing the dispersion of constituents in concrete by electrical resistivity

摘要

Characterization of the degree of dispersion of constituents in cemen paste or mortar by DC electrical resistivity measurement was demonstrated for the constituent being much more conducting than cement (i.e., short carbon fiberts) and much less conducting than cement (i.e., latex particles). The fiber dispersion is described by the ratio of the measured conductivity to the calculated value. The latex particle dispersion is described by a factor in an electrical conduction model.
