Cormix SP1 is a highly effective water reducing super plasticiser 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. Based on the soluble salt of a polymeric sulphonate it conforms to Type A and F materials of ASTM C494 and BSEN 934-2 1998.

Cormix SP1 may also be used where substantial water reductions are required to provide high early and ultimate strengths e.g. in precast factories.

Advantages include
- High strength concrete produced at normal workability and cement contents. The resultant concrete is of a dense impermeable nature.
- Substantial increase in workability without additional water.
- Normal setting without retardation.
- Very good early strengths.
- Significant strength increases.
- Increased production in precast yards.
- Better surface finish.
- Waterproof concrete may be achieved.
- Better resistance to wear & abrasion.
- Chloride free.
- Reduced shrinkage & creep.
- Suitable for hot climates.
- Improved water borne salt resistance.

Compatibility with Cements
Cormix SP1 can be used with all types of Portland Cement and pozzolanic materials.
Cormix SP1 is compatible with P.F.A., G.G.B.F.S. and Silica fume. For use with special cements we recommend that you consult Cormix International Ltd.

Compatibility with Other Admixtures
Cormix SP1SP1should not be premixed with other admixtures. Consult Cormix when using other admixtures.

Cormix SP1 is supplied ready for use, it should be added to concrete mixes during the mixing process at the same time as the water or the aggregates. It should not be added directly to the cement.

DOSAGE
0.5 - 3.0% by weight of cement.
Exact dosage rates should be determined by trial mixes.
TYPICAL STRENGTH DEVELOPMENT USING CONMIX SP1

EFFECTS OF OVER - DOSING
Over-dosing of Conmix SP1 will generally produce a considerable increase in workability. Providing over dosed concrete is properly cured the ultimate strength will generally be higher than of a normal concrete.

Cormix SP1 is formulated from chemicals which present no fire or health hazards. Do not take internally. If on skin wash off with soap and water. If in eyes wash out with copious amounts of water and seek medical attention. For further information consult Cormix International Ltd
