Backfill material for grounding applications
An electrically conductive and swellable backfill material for grounding applications comprising an electrically conductive material selected from graphite, coke powder, and combinations thereof, a polyacrylamide powder, a binder comprising cement, and optionally a salt selected from magnesium sulfate, sodium sulfate, and combinations thereof. This unique backfill material allows it to be used in low humidity areas because it has a low resistivity, a high water absorption and a non-leached behavior.
一种用于接地应用的导电且可溶胀的回填材料，其包含：选自石墨、焦炭粉及其组合的导电材料，聚丙烯酰胺粉末，包含水泥的粘合剂，以及任选的盐，所述盐选自硫酸镁、硫酸钠及其组合。这种独特的回填材料使得其能够在低湿度区域中使用，因为其具有低的电阻率、高的吸水性和不易浸出的行为。
