Plast 455(I)

DESCRIPTION:

AT-PLAST 455 (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.

STANDARDS:

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

USES:

• AT-PLAST 455 (I) is useful where excellent high early strength without stiffening but combined with high water reduction is required.

• AT-PLAST 455 (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

ADVANTAGES:

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

PHYSICAL PROPERTIES:

CONSISTENCY:

• AT-PLAST 455 (I) is formulated from carefully selected raw materials and is manufactured under control conditions produce a consistent product.

HANDLING:

• AT-PLAST 455 (I) is formulated from chemicals, which present no fire or health hazards.

RATE OF ADDITION:

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

DOSAGE:

• For soft plastic concrete 0.6 – 0.85 by weight of cement
• For flowing self-compacting concrete (S.C.C) 0.8 – 1.2% by weight of cement the concrete

ADDITION : AT-PLAST 455 (I) is added to the gauging water or simultaneously with it poured into mixer. For optimum utilization of the high water reduction we recommend thorough mixing at a minimal wet mixing time of 60 seconds. The addition of the remaining gauging water to fine-tune the concrete consistency – may only be started after 2/3 minutes of the wet mixing time to, to avoid surplus water in the concrete.

PACKAGING & STORAGE:

• AT-Plast 455 (I) is available in 250 kg barrel
• Shelf life is 12 months in original & sealed packing
• Keep packing in cool, dry place away from heat, cold and moisture
• Stir material well before use

HEALTH & SAFETY:

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