Sika® Stabilizer-510 MBF Liquid Concentrate

HIGH RANGE WATER REDUCING ADMIXTURE

 Sika® Stabilizer-510 MBF Liquid Concentrate is a high range water reducing admixture that improves the performance of cemented paste fills and high density fills in underground backfill operations. The product is well suited for a range of gold deposits (orogenic, quartz Iode hosted gold) as well as  polymetallic base metals deposits.  

  • Reduction of the cement content up to 25 %
  • Reduction of CO2 emission
  • Strong water reduction of the paste mix
  • Ideal for remote projects
  • Can be stored in cold temperatures
  • Reduction in transport costs:  no fillers or excess water to transport

Usage

Sika® Stabilizer-510 MBF Liquid Concentrate can be used to:
  • Optimize the cost performances of the paste fill mix by reducing binder content (cement, slag, fly ash)
  • Improve the rheological properties of the cemented paste fill during the continuous mixing, pumping, and filling process
  • Enhance workability of the paste fill, allowing long transportation along paste lines at significantly lower water contents
  • Lower the paste yield stress at an increased overall solid content
  • Reduce pumping- and line pressure within the reticulation system
  • Reduce the risk of blockages in the reticulation system
  • Improve in-situ compressive strengths at the final stage
  • Reduce wear and tear of machinery, equipment and paste lines
  • Reduce segregation and bleeding of the placed paste fill
  • Reduce shrinkage and permeability in hardened fill
  • Improve cleaning operation of the mixer and the pumping pipes.

Advantages

  • Reduction of the cement content up to 25 %
  • Reduction of CO2 emission
  • Strong water reduction of the paste mix
  • Ideal for remote projects
  • Can be stored in cold temperatures
  • Reduction in transport costs:  no fillers or excess water to transport

Application

Application Information

Mixing

Once mixing is done, the mixture can be transferred to the storage tank and can be dosed by a liquid dispenser, please refer to the Dosage section.

Restrictions

  • Storage temperature should be lower than 35 °C
  • If a Tote of product freezes product needs to be homogenized and/or fully used
  • Protect from direct sunlight
Consumption

Recommended Dosage

The recommended dosage based on the solid phase is between 0.80 and 1.50 kg per 100 kg of cement. It is recommended to use an automated continuous process liquid dispensing system; the admixture can then be added directly into the plant mixer. It is not recommended to use this product at a higher dosage then the specified maximum dosage, unless required otherwise and after the required tests have been carried out. 

Application steps

APPLICATION INSTRUCTIONS

Dissolution of the admixture : Mechanically, mix a tote of 1040 L of Sika® Stabilizer-510 MBF Liquid Concentrate with 1820 L of water for a minimum of 10 minutes or until a homogeneous mix is obtained.  To obtain the most optimal mix possible, make sure that the selected type of mixer is approved by a Sika Technical Sales Representative beforehand. Once mixing is done, the mixture can be transferred to the storage tank and can be dosed by a liquid dispenser, please refer to the Dosage section.
