Sodium Naphthalene Formaldehyde produces concrete with extremely
workable characteristics referred to as high slump. PNS also allows
concrete to be produced with very low water/cement ratios at low or
Sodium Naphthalene Formaldehyde is ideal for use in prestress,
precast, bridge deck or any concrete where it is desired to keep
the water/cement ratio to a minimum and still achieve the degree of
workability necessary to provide easy placement and consolidation .
