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.
