DESCRIPTION:
AT-PLAST 500 (I) is a highly effective water-reducing agent cum retarding admixture for high performance concrete. This has high plasticizing effect and also acts as a high range water reducer and integral waterproofing for cement. Does not contain any added Chloride.
STANDARDS:
It complies with IS : 9103, IS : 2645 and ASTM C 494/C 494M -99a Type F & G
USES:
- AT-PLAST 500 (I) is useful where excellent high early strength without stiffening but combined with high water reduction is required.
- AT-PLAST 500 (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 air entraining agents
- Non-toxic, does not promote corrosion
- Ultimate strength is not affected
- Also suitable at very low atmospheric temperature

CONSISTENCY:
- AT-PLAST 500 (I) is formulated from carefully selected raw materials and is manufactured under control conditions produce a consistent product.
HANDLING:
- AT-PLAST 500 (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 0.20 – 1.2 by weight of cement
- For flowing self-compacting concrete (S.C.C) 0.5 – 1.5% by weight of cement the concrete
ADDITION :
AT-PLAST 500 (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 minimum 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.
