Sika® Stabilizer-211 MBF

SUPER-PLASTICIZING AND WATER REDUCING ADMIXTURE FOR MINE BACKFILL 

Sika® Stabilizer-211 MBF is used by the mining industry as a normal setting, high-range water reducing, super-plasticizing admixture for hydraulic and paste backfill applications.

• Improved workability with no loss in strength
• Improved stability of the mix during transportation
• Higher strenght may be achieved more economically through water reduction
• Higher, early and ultimate strength
• Reduce segregation
• Improve bleeding time
• Reduce blockages of pipelines
• Reduce drainage time and reduce filling cycles
• Reduce the cement and associated CO2 emissions
• Lower permeability and greater durability

Usage

• For hydraulic and paste backfill operations
• Used as a super-plasticizer, Sika® Stabilizer-211 MBF may be added with the normal amount of water to produce flowing hydraulic or paste backfill mixes
• When used as a water reducer, Sika® Stabilizer-211 MBF will reduce water requirements, increasing the compressive strength at all ages
• Alternatively, it can be used to achieve a combination of these characteristics  

Advantages

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 4% 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.
Application steps

MIXING

Should be dispensed separately from the other admixtures, preferably after all of the materials have been charged into the mixer.
