TYTRO® MF 120

High-performance plasticizing and water-reducing admixture for mine backfill mixes

TYTRO® MF 120 is an aqueous water-reducing admixture specifically formulated to enhance the properties of cementitious mine backfill. Manufactured under closely controlled conditions to provide uniform, predictable higher quality performance, GCP’s TYTRO® MF 120 contains no added chlorides.

Product Advantages

  • Improved rheology – Enhanced flow with reduced water
  • Better pumpability – Reduces pumping pressure and decreases shear viscosity
  • Optimized backfill – Greater economy for a certain level of strength, slump and air
  • Higher strength at all ages
  • Reduces segregation while maintaining flowability
  • Increased uniformity
  • Less permeable/more dense

Uses

TYTRO® MF 120 is used in all mine backfill applications where it is desired to minimize the binder content yet maintaining workability, and especially in the following applications:

  • Paste fill
  • High-density fill
  • Cemented rock fill
  • Hydraulic fill

Addition Rates

The dosage of TYTRO® MF 120 can vary based on the mix design, binder content, and the particle size distribution of the backfill material. The normal dosage range of TYTRO® MF is 300 to 1,300 mL/ton of backfill. Should conditions require using more than the recommended addition rates, please consult your GCP representative.

GCP recommends that trials be performed under local conditions before use to assess and optimize dosage rates and performance.

Mixing & Dispensing

TYTRO® MF 120 can be dispensed directly into the water or the entire wetted out mix. TYTRO® MF 120 should not be dispensed directly on to the dry binder or with other admixtures.

Packaging
