ZM-1B Naphthalene-based Superplasticizer

This product isformed by sulphonation, hydrolyzation and condensation of crude naphthalene.Its chemical name is naphthalene sulfonate formaldehyde condensation and hasstrong dispersibility on cement particles. It can increase strength,compactibility, anti-permeability and other performance of concrete and lowerwater-binder ratio. It has excellent effect on preparing large-fluid concrete,cast-in-place concrete and precast components .
