Abstract

A rigorous round-robin testing program was conducted for surface resistivity (SR) measurements of water cured concrete cylinders in the laboratory. Fourteen different laboratories participated in this effort, testing twelve different Portland cement concrete mixtures containing a wide range of constituent materials. Also, test results from two different commercially available SR meters were compared for statistical equivalence of the data. The results of this effort have been used to formally document the repeatability (single-operator precision) and reproducibility (multilaboratory precision) of SR measurements in the laboratory.
