DOSTFLOW-NP

Sulphonated Naphthalene Formaldehyde  Superplasticizer Powder

PRODUCT DATA SHEET

Description:

DOSTFLOW-NP possesses a powerful water reducing and dispersing ability, whereby high strength, flowing and self leveling concrete can be produced.  DOSTFLOW-NP improves flow properties of concrete by dispersing cement particles and preventing floc formation.

Application

The exact dosage of DOSTFLOW-NP in each mix design would depend upon the ultimate application requirements and may have to be arrived at by actual site trials.  However, incorporation of DOSTFLOW-NP is used to achieve the following concrete characteristics.

Application areas:

  • Ready mix concrete
  • Pre-cast and Pre-stressed concrete
  • Areas of congested reinforcement
  • To reduce water contents for sake of improved impermeability and durability
  • Marine concrete
  • Architectural concrete
  • Pumped concrete
  • Special concrete slabs

Advantages:

  • Improved workability (by maintaining same water cement ratio)
  • Higher early and ultimate compressive strength by lowering water cement ratio
  • Upto 30% water reduction can be achieved by using optimum dosage of DOSTFLOW-NP.
  • Flowing and Self leveling concrete
  • Strong plasticizing effect without any tendency to segregation
  • Very high strength
