Sodium Naphthalene Sulphonate as a Superplasticiser
Sodium naphthalene sulphonate–formaldehyde condensate (SNF) is the most widely used first-generation concrete superplasticiser. Adsorbing onto cement particle surfaces, it increases electrostatic repulsion between particles, dramatically reducing water demand while maintaining workability. SNF-type superplasticisers achieve water reduction of 15–25%, enabling higher-strength concrete mixes. The same dispersant mechanism makes SNF an effective dispersant for dyes, pigments, and agrochemical powders.
