Solving Cathodic Protection Failures in Reinforced Concrete: MMO Coated Mesh Discrete Anodes by Tiaano
Reinforced concrete infrastructure across Australia faces severe structural risks due to chloride-induced corrosion and carbonation. Traditional Cathodic Protection systems often struggle with localized rebar degradation, uneven current distribution, and premature anode consumption in heavily congested reinforced structures. Tiaano addresses these critical challenges with its advanced MMO Coated Mesh Discrete anodes, engineered specifically for high-durability impressed current cathodic protection (ICCP) systems.
The Challenge in Cathodic Protection Infrastructure
Corrosion in marine, industrial, and coastal concrete environments weakens structural integrity long before visual spalling appears. Standard ribbon or tubular anodes frequently suffer from high electrical resistance, hot-spotting, or mechanical displacement during grout encapsulation. Ensuring long-term structural reliability requires uniform current flow directly to dense, targeted rebar zones without compromising structural integrity.
Key Benefits & Technical Specifications
Tiaano's MMO Coated Mesh Discrete systems provide a targeted, robust solution for localized and complex concrete cathodic protection applications.
o Superior Current Distribution: The mesh structure provides an expanded surface area, lowering anode-to-concrete contact resistance and delivering uniform protective current.
o Targeted Installation: Discrete positioning allows precise placement in high-corrosion zones, rebar-dense locations, and complex structural joints.
o Extended Service Life: Engineered for design lives exceeding 50 to 100 years under standard operating current densities.
Material Selection & Technical Properties
ü Base Substrate: Grade 1 or Grade 2 ASTM B265 Titanium mesh substrate, providing ultra-lightweight strength and exceptional corrosion resistance.
ü Electrocatalytic Coating: Mixed Metal Oxide (MMO - IrO₂/Ta₂O₅) thermally applied to ensure high electrocatalytic activity, stability, and minimal consumption rates.
ü Conductor Bar Integration: Integrated pure titanium conductor bars enable seamless spot-welding and continuous electrical connectivity across anode zones.
ü Ribbed Insulating Spacers: Integrated non-conductive rib spacers ensure precise concentric positioning within drilled slots or boreholes, preventing direct short-circuiting against structural steel reinforcement.
Quality Assurance & Manufacturing Excellence
Tiaano enforces stringent Quality Assurance (QA) and Quality Control (QC) protocols throughout production. Every MMO Coated Mesh Discrete anode undergoes rigorous substrate surface preparation, precision thermal coating deposition, adhesion testing, accelerated life testing (NACE TM0294/ISO 12696 standards), and dimensional verification to guarantee optimal field performance.
Applications Across Australian Infrastructure
Tiaano’s discrete anode solutions excel in critical asset preservation across Australia:
1. Marine Structures: Jetty piles, wharf decks, seawalls, and port infrastructure exposed to severe tidal zones.
2. Civil & Transportation: Bridge decks, substructures, multi-story parking facilities, and underground tunnels.
3. Industrial Assets: Foundation slabs, water treatment facilities, and coastal industrial plants.
