The test method ASTM C 1202 is critically examined in this paper. It is observed that the total charge passed is not a good basis for classification of concrete quality when different binders(such as fly-ash, bottom ash and silica fume etc etc) are considered. A change of voltage and simple modification test method are examined. The modification involved performing of additional test using distilled water as electrolyte. The difference in the total charges passed obtained between change of voltage in concrete and test performed in water is suggested as an indicator for concrete quality. The chloride ion penetration for concrete with mineral admixtures can correctly estimated in considring pozzolan reacts with long term ages of the concrete.
