Plast 205(I)

DESCRIPTION:

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.

STANDARDS:

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

USES:

• 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

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

TECHNICAL DATA:

CONSISTENCY:

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

HANDLING:

• AT-PLAST 205 (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 0.60% – 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.

PACKAGING & STORAGE:

• AT-PALST 250 (I) is available in 250 kg HDPE container
