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
  1. Compressive strength at all ages increases by about  25 to 50 %  Helps to  reduce  cement  content for  a given  strength
  2. Produces flowing concrete with better than normal strength.
  3. Improves workability and makes concrete denser and impermeable
  4. Developes higher early strength than that required in precast work with OPC (Type 1) cement.
  5. Increases cohesion, minimizes segregation and bleeding, giving a better surface finish.
  6. Reduces water content about 20 - 30 % for the same workability.
APPLICATIONS
  1. Ready mix concrete
  2. High slump, flowing concrete
  3. Heavily reinforced concrete
  4. Flatwork and mass concrete
  5. 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.
