  • Compressive strength gain, Concrete, Naphthalene based

    Naphthalene based superplasticizer (SNF) is produced from naphthalene by oleum or sulfur trioxide sulfonation of β sulfonate. Subsequent reaction with formaldehyde leads to polymerization and the sulfonic acid [4] as shown in Figure 1. It is then neutralized with a suitable alkali and filtration to eliminate calcium sulfate [15]. Figure 1.
