An Ofite Resistivity Meter was used to measure resistivity of a mud sample five times. The average resistivity is 0.98 ± 0.01 ohm-m. From each obtained resistivity at a temperature of 73 degrees Fahrenheit, a salinity …
More DetailsIn all cases, the total chloride content, i.e. free and bound, is determined. Finally, the chloride content is calculated with respect to dry concrete weight (wt.%) and/or with respect to the cement content of the concrete if it is known. For potentiometric titration, ammonia is added to the filtrate to increase the pH towards neutral values.
