SPECIFICATION

Naphthalene sulphonate as Superplasticizers :

Naphthalat K Based superplasticisers disperse the flocculated cement particles through a mechanism of electrostatic repulsion In normal plasticisers, the active substances are on to the cement particles, giving them a negative charge, which leads to repulsion between particles. Naphthalene and melamine superplasticisers are organic polymers. The long molecules wrap themselves around the cement particles, giving them a highly negative charge so that they repel each other.
