Water Reduction: SikaPlast®-440 can be dosed at low to medium quantities to obtain water reduction from 5-18% and will achieve water reduction up to 22% at high dosage rates. Extended Slump Life and Set Control: SikaPlast®-440 has been formulated to provide controlled and predictable extended slump life for periods of 90 to 120 minutes (depending on dosage) allowing good slump retention without significant loss in early strength development. The combined high range water reduction and plasticising action of SikaPlast®-440 provides the following benefits in hardened concrete:

• Higher early compressive strengths for earlier removal of forms and structural use of concrete.
• Higher ultimate strengths allow for greater engineering design flexibility and structural economies.
• Reduced water cement ratios produce more durable, dense concrete with reduced permeability.

SikaPlast®-440 does not contain formaldehyde, calcium chloride or any other added chlorides and will not initiate or promote the corrosion of steel present in the concrete.
