CORMIX SF1

An ultrafine spherical, high performance super reactive pozzolanic mineral additive conforming to ASTM C1240 definitions.

For dense, durable, watertight & high strength concrete. Use in shotcrete to reduce rebound, decrease permeability and improves strengths.

2-15% by weight of cement.

CORMIX AFL

An alkali-free liquid admixture formulated to provide set acceleration in shotcrete, while reducing with traditional alkaline shotcrete accelerators. Complies to ASTM C1141, Type II & Grade 9, Class A.

For wet & dry shortcrete in tunnels, mines, concrete repair & slope stabilization etc.

3-10% by weight of cementitious material.

CORMIX AFL RT1

An alkali-free liquid admixture formulated to provide faster hardening acceleration in shotcrete. Complies with ASTM C1141, Type ll & Grase 9, Class A. BSEN 5075-1:1982

Used with shotcrete in tunneling, mining, concrete repair and slope stabilization.

3-10% by weight of cementitious material.

CORMIX AFP

An alkali-free powder admixture formulated to provide set acceleration in shotcrete, while reducing the safety hazards associated with traditional alkaline shotcrete accelerators. Complies to ASTM C1141, Type I & Grade 9, Class B..

Suitable for use with shotcrete in tunnels, mines etc. and for slope stabilization.

3-7% by weight of cementitious material.

CORMIX TLA

An admixture for use in shotcrete applications to improve shotcrete both in its hardened & plastic state.

Used where a high quality shotcrete is required with better bond, and lower permeability.

Approx. 5 kg/m3 of shotcrete.

CORMIX LA1

A liquid accelerator used for cementitious grouting in tunnels driven by TBMs.

For use in tunnel cavity grouting applications where an early strength is required for the backfill grout.

See data sheet.

CORMIX SP1/B

A highly effective water reducing superplasticiser and an extremely powerful de-flocculating agent, it operates by dispersing cement in to its primary particles which dramatically increases the flow characteristics of the cement paste. Complies with ASTM Type A&F and BSEN 934-2.

For using both in precast concrete & R.M.C. applications. Uses include to produce flowing concrete in congested areas, slabs and foundations, large pours, beams, columns and precast elements.

0.5-3.0 litre per 100 kg of total cementitious material.
