ANODES - BACKFILL

Loresco SC-3®, due to its dust-free manufacture, is simple to install by either mixing and pumping or by pouring. With deep anode systems, pumping from the bottom up is recommended. Loresco SC-3® has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of heavy mud. A recommended mix is seven gallons of water per one hundred pounds. After installing SC-3®, allow twenty-four hours settling time before energizing. The modified surface of the carbon particles coupled with the action of the surfactants in SC-3® will achieve positive electrical contact by settling. Vibrating or compacting is not necessary.

Material Description:

Loresco SC-3® is a surface modified, blended, and sized carbon backfill with surfactants.

Specifications:

• Bulk Density: 74 lbs. per cubic foot
• Predominantly round particles
• All particles surface modified for maximum electrical conductivity
• Particle Sizing: To be dust free with a maximum particle size of 1 mm
• Minimum calcination temperature of base materials is 1250° C
• Base materials are calcined under ISO 9002 quality control
• Surfactants are added to assist pumping and settling
• No de-dusting oils are used during the manufacture of base particles

Shipping Data:

Loresco SC-3® is shipped in fifty (50) pound (22.7 kg) coated, woven polypropylene bags. SC-3® may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fifty bags per pallet. Proven export packaging is also available.

Loresco SWK® may be poured freely in dry applications. Tamping is not required. if SWK® is poured through water or light mud, the rate of pouring should not exceed the rate of SWK®'s wetting and sinking. The rate of pouring through water will be approximately one hundred pounds per two minutes.

Horizontal Installation Procedure:

• Have a reasonably clean ditch (design usually calls for a ditch one foot wide).
• Pour Loresco SWK® in a continuous layer six inches deep (or as specified).
• Place anodes on top of SWK®.
• Pour SWK® in a continuous layer until anodes are covered by a six inch backfill cover (or as specified).
• Fill the remainder of the ditch as specified.

Vertical Installation Procedure:

• Have a reasonably clean hole (depth depending on soil resistivity).
• Place one foot of SWK® in bottom of hole.
• Lower and center anode in proper position.
• Pour SWK® over anode until design level is reached.
• Fill remainder of hole as design specifies.

Specifications:

• Bulk Density: 70 lbs. per cubic foot.

• Particle Sizing: Ranging from 0.1 to 12mm.
