Basic attributes of naphthalene-based water reducers

Naphthalene-based water reducers are high-efficiency water reducers made from naphthalene as the primary raw material with chain reaction such as sulfonation and condensation. They are anionic surfactants. Rigid naphthalene rings and hydrophilic sulfonic acid teams define its molecular structure. This structure enables it to efficiently adsorb externally of concrete particles and disperse cement fragments via electrostatic repulsion. The water reduction rate of naphthalene-based water reducers is generally in between 15% and 25%. It has good versatility and is well-compatible with most cement.
