Naphthalene Based Superplasticizer Powder
TDS Technical Document Sheet 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.
Technical Specifications
Chemical Classification: Sodium salt of polynaphthalene sulphonic acid
Appearance and form: Beige to brownish free flowing powder
Solid content: 94 ± 1%
pH of 10% solution: 7 - 9
Bulk density g/cc: 0.6 ± 0.02
Ionic nature: Anionic
Solubility: Soluble in water in all proportions
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
Storage and shelf life:
DOSTFLOW-NP is supplied in 25 kgs paper bags. It is recommended to store DOSTFLOW-NP at around 25-30 °C in original packing protected from direct sunlight. When stored under recommended conditions the shelf life would not be less than 1 year.
Packaging
25 kg plastic bags.
