Plast 205(I)


AT-PLAST 205 (I) is a highly effective water-reducing agent and super plasticiser for promoting accelerated hardening and free flowing concrete. Does not contain any added Chloride.


It complies with IS: 9103 and ASTM C 494/C 494M -99a Type E


  • AT-PLAST 205 (I) is useful where excellent high early strength without stiffening but combined with high water reduction is required.
  • AT-PLAST 205 (I) is used for the following types of concrete:
    • Ready mix concrete
    • Pumped and construction concrete
    • Slip form concrete
    • Concrete at mild to cold temperatures


  • Combination of hardening accelerator and high range water reducer
  • Excellent high early strength
  • Good workability and slump life
  • Compatible with air entraining agents
  • Non-toxic, does not promote corrosion
  • Ultimate strength is not affected
  • Also suitable at very low atmospheric temperature



  • AT-PLAST 205 (I) is formulated from carefully selected raw materials and is manufactured under controlled condition to produce consistent product.


  • AT-PLAST 205 (I) is formulated from chemicals, which present no fire or health hazards.


  • With small dosage the increment of slump is more. The dosage depends on the cement content and the W/C ratio.


  • For soft plastic concrete 0.60% – 0.85% by weight of cement
  • For flowing self-compacting concrete (S.C.C) 0.80% – 1.2% by weight of cement
  • Actual dosage depends on site trial

ADDITION : AT-PLAST 205 (I) M is added to the gauging water or added into the concrete mixer. To obtain the optimum result of high water reduction we recommend thorough mixing at a minimal wet mixing time of 60 seconds. Addition of remaining gauging water to be fine-tuned as per concrete consistency, the same may only be started after 2/3 minutes of the wet mixing time to avoid surplus water in the concrete.


    • AT-PALST 250 (I) is available in 250 kg HDPE container
    • Shelf life is 12 months in original & sealed packing
    • Storage condition should be free from frost and protect from direct sunlight
    • Keep packing in cool, dry place away from heat, cold and moisture
    • Stir material well before use


  • Protect hands with rubber gloves and eyes with goggles.
  • Accidental splashes to the skin or eyes must be rinsed immediately with clean water.
  • Store in well-labeled containers.
