High-performance ultrafine cement powder designed for critical injection, consolidation, and sealing works in mining, tunnelling, and civil construction.

Technical Data

 Ultrafine-12 undergoes regular in-house quality control, including laser diffraction particle size analysis. Results are periodically verified externally by NATA-accredited laboratories.

Note: These values are typical and subject to change based on manufacturing conditions. Performance-based properties, such as compressive strength, set times, bleed, etc, are highly dependent on water-to-solids (w:s) ratios, addition of admixtures, and end-user applications and requirements.

Product Description

Ultrafine-12 is a high-performance ultrafine cement powder designed for critical injection, consolidation, and …

Ultrafine-12 is a high-performance ultrafine cement powder designed for critical injection, consolidation, and sealing works in mining, tunnelling, and civil construction. With a d95 particle size of ≤12 μm and laser diffraction specific surface area (SSA) of ≥1000 m²/kg, it enables effective penetration of tight fractures, porous zones, and fine soils where conventional cementitious grouts cannot reach.Produced through air classification of high-quality general purpose cement conforming to AS 3972 (Type GP), BMS Ultrafine-12 avoids additional mechanical milling while achieving a refined and consistent particle size distribution. This controlled manufacturing process results in a dry, free-flowing powder with high reactivity and predictable setting time, making it ideal for demanding underground and surface grouting environments.BMS Ultrafine-12 is compatible with a wide range of additives, including plasticisers, retarders, and accelerators, and may be used as a stand-alone grout or in engineered mix designs to suit project specifications or performance requirements

  • Cement dust is an irritant—avoid inhalation or skin/eye contact.
  • Wear protective gloves, clothing, eye and face protection.
  • Ensure adequate ventilation during mixing and application.
  •  In case of contact with the eyes, rinse with running water for 15 mins and remove contaminated clothing.
  •  Always consult the Safety Data Sheet (SDS) prior to handling or use.
  • In an emergency, contact any Poisons Information Centre (Phone: 13 11 26 within Australia)…
