Sika® Stabilizer-314 MBF

HIGH-RANGE WATER REDUCER FOR MINE BACKFILL

Sika® Stabilizer-314 MBF is a high-range water reducing admixture used by the mining industry to improve the performance of cemented paste fills for underground backfill operations. The product is well suited for a range of polymetallic base metals deposits ( volcanogenic massive sulfide), and for gold deposits (orogenic, quartz Iode hosted gold). 

  • High water reduction, resulting in high density and high compressive strength
  • High plasticizing effect, resulting in improved flowability and placement
  • Does not contain chlorides or any other ingredients which promote the corossion of steel
  • Reduction of the cement content and associated CO2 emissions

Usage

Sika® Stabilizer-314 MBF can be used in mining to : 
  • Reduce water and increase solid content of the cemented paste fill
  • Enhance workability of the paste fill 
  • Improve rheological properties to facilitate mixing and pumping, and increase backfill throughput
  • Reduce pumping and line pressure within the reticulation system
 
  • Improve in-situ compressive strengths at the final stage
  • Reduce costs by reducing binder content (cement, slag, fly ash)

Advantages

  • High water reduction, resulting in high density and high compressive strength
  • High plasticizing effect, resulting in improved flowability and placement
  • Does not contain chlorides or any other ingredients which promote the corossion of steel
  • Reduction of the cement content and associated CO2 emissions

Application

Consumption

Recommended Dosage

The dosage to be used should be estimated by preliminary laboratory testing. The recommended dosage will usually be between 1 and 3% by weight of the total cementitious content. It is suggested than an automated liquid admixture dispensing system adapted to the paste backfill mixing method be used. Start plant trials with a lower dosage than that estimated in the laboratory. If the performance and the system results are satisfactory, continue with this dosage. If performance is unsatisfactory, gradually increase the dosage while continuously monitoring the system until the desired performance is achieved. Do not use a higher dosage than the recommended without preliminary testing.
