Product introduction Embedded Galvanic Anodes

Sacrificial Anode, made of a zinc metal core, is a protective coating used on concrete surfaces and metal reinforcements to enhance and strengthen the rebar. This product significantly increases structures’ lifespan, durability, and stability over an extended period. Afzir Company recommends using sacrificial anodes for contractors and builders due to their ease of installation, quick implementation, and cost-effectiveness compared to other retrofitting and improvement methods.
The protective properties of sacrificial anodes stem from their highly negative reduction potential. When the sacrificial anode is close to a metal with a higher reduction potential, it converts that metal into a cathode. By utilizing the flow of current, it transfers oxidizing agents through electrons. As a result, the sacrificial anode is consumed instead of the vital metal present in the desired structure, such as steel reinforcement. Structures or constructions equipped with sacrificial anodes can maintain their mechanical properties for many years, ensuring optimal performance. Consequently, such structures have significantly longer service lives compared to conventional ones.
Sacrificial anodes of alloy type 1 are specifically formulated in saltwater or marine environments. They find extensive applications in reservoirs, pipelines, docks, vessels, and other marine settings.
Sacrificial anodes of alloy type 2 incorporate standard alloys and are effective in freshwater and buried structures in soil. These anodes can be used with or without backfill.

Price of Sacrificial Anodes:

The mass and dimensions of sacrificial anodes significantly impact their performance. A higher mass implies a longer lifespan before depletion. Therefore, it is essential to determine the desired mass and dimensions of sacrificial anodes based on the intended objectives before procurement. The price of sacrificial anodes varies depending on factors such as dimensions, purity percentage, weight, the presence or absence of backfill, alloy type, and market fluctuations.

For Engineers Embedded Galvanic Anodes

Our product is designed to enhance efficiency and improve the performance of structural elements by utilizing anodes to extend their life cycle. With the assistance of a zinc metal core, it generates a small electric current that effectively safeguards concrete and steel reinforcements from corrosion. This proactive protection mechanism significantly contributes to the longevity and durability of the structures, ensuring their optimal performance over time.

For Contractors Embedded Galvanic Anodes

The sacrificial anode serves as a protective coating for concrete, applied to both concrete surfaces and metal reinforcements to enhance and reinforce the rebar. By effectively extending the lifespan, strengthening durability, and ensuring long-term stability, this product significantly contributes to the structure’s overall strength. Afzir Company highly recommends the sacrificial anode product to contractors and builders, citing its ease of installation, efficiency, and cost-effectiveness when compared to alternative retrofitting and improvement methods.

Application Instructions Embedded Galvanic Anodes

Surface Preparation:

To ensure optimal adhesion and strength, it is imperative to prepare the surface appropriately. Begin by removing any loose or delaminated concrete as per the recommended guidelines. Clearly mark the desired area and eliminate damaged concrete from the surface. It is crucial that both the desired surface and reinforcement are thoroughly cleaned and free from any extraneous materials.

Placement:

The anode should be carefully positioned in the desired area, creating a suitable layer over the reinforcement. Additionally, ensure that all joints on the reinforcement surface are adequately covered with repair mortar. For effective electrical connection and optimal anode performance, it is important to note that only structures with uncoated steel reinforcement are suitable. The continuity and durability of the electrical connection must be verified through an armature test. This can be achieved by employing common methods such as wire connections or welded connections. To establish an electrical bond, hand-tighten two pairs of pre-twisted wires around the steel armature, enclosed within a double sheath. Twisted wire connections enable a proper electrical connection at a specific distance from the location of the anode on the steel armature.
