CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING JOINT FILLERS WATERPROOFING WATERSTOPS ROOFING TIMBER FLOORING ALPHABETICAL INDEX 95 anode units as manufactured by Vector Corrosion Technologies and supplied by Parchem Construction Supplies. The distributed galvanic anode units shall be alkali-activated with a pH greater than 14 and contain zinc evenly distributed along the length of the unit. Zinc shall be in compliance with ASTM B418 Type II (Z13000) and ASTM B6 Special High Grade (Z13001) with iron content less than 15 ppm. The zinc shall be formed around a steel core which is continuous along the length of the unit. The anode unit shall include FRP reinforcing to resist expansion, and shall not contain added sulfates, nor constituents that are corrosive to reinforcing steel as per ACI 222R such as chlorides, bromides, or other halides. Unless otherwise specified, the anode unit shall be supplied with a pair of integral heattreated, uncoated steel tie wires with loop ties to make connections to the reinforcing steel. Design Criteria Galvanode DAS distrubuted anode system can be used for corrosion prevention, corrosion control or cathodic protection applications. Anode design and spacing are varied to meet project objectives. Anode spacing generally ranges between 150 mm and 750 mm on center depending upon project objectives, the severity of the service environment and expected service life of the anode components. For assistance with system advice, please contact Parchem Construction Supplies.

Typical anode weights are listed above. Installation Instructions Galvanode DAS distributed anode system is used for a wide range of applications. Specific application procedures are developed on a project-by-project basis. For additional information, please contact Parchem Construction Supplies. Precautions Galvanode DAS distributed anode system is not intended to address or repair structural damage. Where structural damage exists, consult a structural engineer. Do not allow Galvanode DAS anode units to be soaked prior to installation. For optimum performance, encasement concrete, grout or repair mortar resistivity should be less than 15,000 ohm-cm. Products such as Galvashield MC50 grout or Renderoc LA55 meet this criteria. Concrete with significant amounts of polymer or silica fume may have higher resistivity. For applications where wetting will occur such as in tidal zone protection, use Galvanode DAS Marine anode units. Packaging The Galvanode DAS Distributed Anode System is custom packaged based on project requirements. For additional information, contact Parchem Construction Supplies. Storage Store in dry conditions in the original unopened containers for up to one year from date of manufacture. System should be installed within one month of opening container. Take special precaution not to damage anode components during transportation or while handling. Avoid extremes of temperature and humidity. Shelf life Shelf life 12 months. Health and Safety Contact with moisture can release alkalis which may be harmful to exposed skin. Anode components should be handled with suitable gloves and other personal protective equipment in accordance with standard procedures for handling cement and other alkaline materials. Additional safety information is included in the Material Safety Data Sheet.
