WATCHEM SUPERPLAST
SUPERPLASTICIZER (HIGH RANGE WATER REDUCER ) |
| DESCRIPTION |
Watchem SUPERPLAST is specially formulated admixture based on organic polymer and selected additives . It is supplied as dark brown coloured liquid miscible with water. It can be added to concrete mix at the job site or at ready mix concrete plant. |
STANDARD
Confirms to IS: 9103:1999 and ASTM –C 494M – 99a,1999 Type A & F , as superplasticizer / high range water reducing admixture. |
SALIENT FEATURES
- Compressive strength at all ages increases by about 25 to 50 % Helps to reduce cement content for a given strength
- Produces flowing concrete with better than normal strength.
- Improves workability and makes concrete denser and impermeable
- Developes higher early strength than that required in precast work with OPC (Type 1) cement.
- Increases cohesion, minimizes segregation and bleeding, giving a better surface finish.
- Reduces water content about 20 - 30 % for the same workability.
|
APPLICATIONS
- Ready mix concrete
- High slump, flowing concrete
- Heavily reinforced concrete
- Flatwork and mass concrete
- Prestressed concrete
|
DIRECTIONS FOR USE
Watchem SUPERPLAST is added to pre-wetted concrete mix at a rate of 0.4 to 0.6 Lt. per bag of cement. However actual site trials have to be carried out to minimize the optimum dose for the intended application.
The measured quantity of Watchem SUPERPLAST is mixed with part of gauging
water and then added to the mix. For further assistance in optimum dosage trials
and design mix please contact our TECHNICAL SERVICE DEPARTMENT.
