Grounding net is necessary to ensure the security of electrical equipment and personal safety for the high voltage transmission tower. The grounding resistance under power frequency of the grounding net must meet the national standard. The normal resistance-reducing agents show conductivity instability, short service life and poor water-retaining property. The conductive concrete is capable of good permeability, water-retaining property and conductivity. While there is a contradiction between the high mechanical strength and good conductivity. In this paper, the acrylic acid emulsion is used to increase the adhesion stress between the steel fibers and the concrete. © (2015) Trans Tech Publications, Switzerland.
