It is a corrosion-resistant zinc anode encased in a mortar with alkalinity equal to or greater than 14 (PH≥14), providing an electric current to effectively protect the reinforcing steel from rusting and extending the life of structural steel in concrete structures such as residential buildings, foundations of factories, bridges, ports, wharfs, and other buildings. The Zinc Anode for rust prevention is shaped like a mortar ball and can be easily tied with wire or fastened with metal belts onto the reinforcing steel giving protection against rust for up to 10 years when calculated and installed according to the instructions in the calculation document for installing TMP Concrete Anode.
