Sodium Naphthalene Sulphonate 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 normal slumps.
Sodium Naphthalene Sulphonate 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
Sodium Naphthalene Sulphonate Formaldehyde can be added directly or
added in after melt. It can be added during mixing and
after-mixing. The afterward approach can achieve better result. The
suggested addition rate is 0.75%.
Sodium Naphthalene Sulphonate Formaldehyde Direction
Prepare solutions as required.
Direct use of powdery agent is allowed. Alternatively the addition
of the agent is followed by water moisturization (water-cement
The agent can be combined with other externally applied agents if
pilot development or laboratory experiment succeeds.
