Loresco RS-3 is the newest and most innovative super conducting earth contact backfill in the Loresco product line. RS-3 combines the characteristics of superior low resistivity and high bulk density with a remarkably rapid sinking ability to provide the latest in conductive carbon backfill technology. Because of the new rapid sinking ability RS-3 is able to achieve maximum compaction quickly. Rapid sinking allows for a faster construction completion time and faster energizing of the anode system. Rapid sinking allows for pouring when pumping is not an option. RS-3 is able to handle the demands of stringent field requirements. This is the first time a conductive carbon backfill combining pumping ability and pouring ability has been available in one bag. RS-3 is manufactured under a new process which creates a new surface with superior conductive properties. This manufacturing process is exclusive to conductive carbon formulations designed for cathodic protection. The new manufacturing process ensures the impressed current anode and RS-3 system have increased electronic flow performance to further increase the life of the anode system. Loresco RS-3 is produced specifically for cathodic protection applications using an exclusive multi-step process.
First, a very high quality base carbon with desired characteristics is selected. Next, this carbon is calcined to a minimum temperature of 1250 C under very exacting and controlled standards. This step results in semi-graphitized carbon particles with excellent conductivity. All particles shaped and surface modified for maximum electrical conductivity and high-current applications. Then, to further improve the bulk conductivity, the surfaces of the individual particles are modified to enhance the contact conductance in a process exclusive only to the corrosion industry. This breakthrough in surface alteration ensures maximum electronic current transfer with positive anode contact. Finally, a specially formulated surfactant is added to reduce particle surface tension for compact settling under water.
Loresco RS-3 has a bulk density of 68 lbs per cubic foot. The fixed carbon content is greater than 99 percent by weight. The bulk density and high fixed carbon content coupled with the assured low resistivity medium allows for longer groundbed life at a lower operating cost.
- Bulk Density 68 lbs. per cubic foot.

Installation:Loresco RS-3, due to its maufacturing process, is simple to install by either mixing and pumping or by pouring dry. With deep anode systems, pumping from the bottom up is recommended. Loresco RS-3 has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of super heavy mud. Time before energizing is greatly reduced after installing RS-3. The modified surface of the carbon particles coupled with the action of the surfactants in RS-3 will achieve positive electrical contact by settling.Vibrating or compacting is not necessary. See installation section on cd or in the catalog for additional pumping data.
Material Description:Loresco RS-3 is a surface modified, blended, and sized carbon backfill with surfactants.
