Plast 401(FW)

DESCRIPTION:

AT-PLAST 401(FW) is a high range water-reducing admixture. It is recommended for concrete at the job site or at the ready mix concrete plant. No Chlorides are used in its formulation hence, it is recommended for pre-stressed concrete. It is also compatible with air entraining agents, water-proofing agents, calcium chloride and many other admixtures; however, each material should be added to the concrete separately.

STANDARDS:

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

USES:

• AT-PLAST 401 (FW) is useful where excellent high early strength without stiffening and high water reduction is required.

• AT-PLAST 401 (FW) is used for the following types of concrete:
  • High performance concrete
  • General ready mix concrete
  • Heavily reinforced concrete
  • Flatwork and mass concrete
  • Minimum water content concrete
  • Low water/cement ratio concrete
  • High slump flow-able concrete

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

PHYSICAL PROPERTIES:

(All technical data stated herein is based on tests carried out under laboratory condition)

CONSISTENCY:

• AT-PLAST 401 (FW) is formulated from carefully selected raw materials and is manufactured under control conditions produce a consistent product.

HANDLING:

• AT-PLAST 401 (FW) 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 0.30% – 0.85% by weight of cement
• For flowing self-compacting concrete (S.C.C) 0.8 – 1.2% by weight of cement the concrete
• Actual dosage depends on site trial

ADDITION :

AT-PLAST 401 (FW) 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 401 (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.
• Store in well-labeled containers.
