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.
