NOVELTY - Conductive mortar, comprises cement, quartz sand, water, sacrificial anode activator and expansion agent, where the weight ratio of the quartz sand and cement is (2.5-4): 1, the weight ratio of the cement and water is 1: (0.50-0.70), the sum of the parts by weight of the cement and quartz sand, and weight ratio of the sacrificial anode activator is 100:(2-5), and the weight ratio of the cement to the expansion agent is 100:(8-15). The conductive mortar comprises cement, quartz sand, water, sacrificial anode activating agent and expanding agent. USE - Used as conductive mortar. ADVANTAGE - The conductive mortar has strong cohesive force, easy forming, small resistivity, promotes internal ion transmission, small porosity, and high ion permeability resistance. The prepared sacrificial anode mortar has good electrochemical activity, without welding lead on the metal surface, to realize the electric connection of the metal and the sacrificial anode, which can cathodic protection the long-term effect of metal surface. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: acrificial anode; preventing metal corrosion.
