WebFeb 17, 2024 · The made ground of mine A (table 10) shows a resistance 20 times higher than the resistance of the track to ground, although the coil of wire making up the grounding component was buried in a creek bed that had water throughout the year. This inconsistency is similar to that observed by Bird and Smith at the Taylor No. 7 well (table 2). WebDescription. This specially formulated anode backfill is used with either magnesium or zinc cathodic protection anodes to lower the anode-to-earth resistance and to help retain moisture around the anode, thus creating a more efficient ground bed. The standard anode mixture consists of 75% gypsum, 20% bentonite and 5% sodium sulfate. bonavest gmbh hamburg
