Plast(MMF)

DESCRIPTION:

AT-PLAST (MMF) is a high range water reducing and accelerating super plasticizer.

STANDARDS:

It complies with ASTM C494: Type A, C, E & F, IS 9103, IS 2645 and BS 5075 : Part I

PROPERTIES:

  • High range water reducer designed to obtain rehoplastic concrete without segregation
  • Reduction of 15-20% water contents whilst maintaining workability, durability & impermeability
  • The increase in strength, especially evident at early ages remains at later ages, both in air cured and steam cured processes
  • Acts catalytically to increase the rate of hardening of cement particles thereby leading to higher early strength
  • Translucent colour enables use with white Cement concrete
  • Produces highly impermeable, dense concrete with enhanced durability
  • Enables precast units to be de-moulded within 12 to 16 hours
  • Increases ultimate compressive strength and other strength developing properties
  • Compatible with all type of cement including sulphate resisting
  • Reduce the placing problems in hot weather concrete
  • Improve trowel ability & surface finish
  • Reduces the incidence of honeycombing and cold joints during vibration
  • Reduce water contents would be of benefit to reduce permeability

APPLICATION AREAS:

  • Pre-cast concrete manufacture
  • White cement concrete
  • In complicated formwork or with congested reinforcement
  • In hot weather condition it extends workability
  • Bridges and cantilever structures
  • Pre-stressed concrete
  • Floor slabs
  • Foundations
  • Walls and columns
  • Beams and slabs
  • For fair face concrete

DIRECTION FOR USE:

  • SETTING TIME
    • AT-PLAST (MMF) acts efficiently to give controlled quick setting.
    • Setting time of concrete mixes is related to cement type and ambient temperatures.
  • EFFECT OF OVER DOSAGE
    • Slightly retardation of initial set
    • Slight increase in air contents
    • Providing the concrete is properly cured, the ultimate strength of the concrete will not be adversely affected and will be generally higher than for normal concrete.
  • MIXING
    • AT-PLAST (MMF) should be added to concrete during mixing cycle at same time as the water and aggregates.
    • Never add AT-PLAST (MMF) to the dry cement
  • DISPENSING:
    • AT-PLAST (MMF) is introduced into the mixer together with mixing water. The plasticizing effect or water reduction is higher if the admixture is added to the concrete after 50-70% of the mixing water has been added.
    • Addition of AT-PLAST (MMF) to dry aggregate or cement is not recommended.
  • CURING:
    • Fresh poured concrete must be cured properly, particular at high temperatures in order to prevent plastic and drying shrinkages and cracks.
    • Use ADO Curing Compounds to achieve best results or apply wet hessians.

PACKAGING & STORAGE:

  • AT-PLAST (MMF) is available in 200 kg HDPE barrel
  • Shelf life is 12 months in original & sealed packing
  • Keep packing in cool, dry place away from heat, cold and moisture
  • Protect against contamination
  • 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.
  • Non dangerous goods, please observe Material Safety datasheet.
