High Range Water Reducer

High Range Water Reducer
High Range Water Reducer
Product Code : PLASTCONE AP 430
Brand Name : Redwop
Product Description

Uses:

 

  • To produce pumpable concrete
  • To produce high strength, high grade concrete M30 & above by substantial reduction in water resulting in
  • low permeability and high early strength.
  • To produce high workability concrete requiring little or no vibration during placing.

 

Advantages:

 

  1. Improved workability - Easier, quicker placing and compaction.
  2. Increased strength - Provides high early strength for precast concrete with the advantage of higher water reduction ability.
  3. Improved quality - Denser, close textured concrete with reduced porosity and hence more durable.
  4. Higher cohesion - Risk of segregation and bleeding minimized; thus aids pumping of concrete
  5. Chloride free - Safe in prestressed concrete and with sulphate resisting cements and marine aggregates.

 

Standards compliance:

PLASTCONE AP430 complies with IS: 9103:1999 and BS: 5075 Part 3. PLASTCONE AP430 conforms to ASTM-C-494

Type 'F' and Type 'A' depending on the dosages used.

 Description:

PLASTCONE AP430 is based on Sulphonated Napthalene Polymers and supplied as a brown liquid instantly

dispersible in water. PLASTCONE AP430 has been specially formulated to give high water reductions upto 25%

without loss of workability or to produce high quality concrete of reduced permeability.

Properties:

Specific gravity: 1.150 to 1.190 at 300C

Chloride content: Nil to IS: 456

Air entrainment: Approx. 1% additional air is entrained

Compatibility: Can be used with all types of cements except high alumina cement. PLASTCONE AP430 is

compatible with other types of PLASTCONE admixtures when added separately to the mix. Site trials should

be carried out to optimize dosages

Workability: Can be used to produce flowing concrete that requires no compaction. Some minor

adjustments may be required to produce high workable mix without segregation.

Cohesion: Cohesion is improved due to dispersion of cement particles thus minimizing segregation and

improving surface finish.

Compressive strength: Early strength is increased up to 20% if water reduction is taken advantage of.

Generally, there is improvement in strength up to 20% depending upon W/C ratio and other mix

parameters.

Durability: Reduction in W/C ratio enables increase in density and impermeability thus enhancing durability of concrete.

Application instructions

Dosage:

The optimum dosage is best determined by site trials with the concrete mix which enables the effects of

workability, strength gain or cement reduction to be measured. Site trials with PLASTCONE AP430 should always
