Abstract:
Four commercial high-range water-reducing admixtures based on naphthlanene-sulfonic acid-formaldehyde condensation products and two commerical admixtures of this type based on melamine-sulfonic acid formaldehyde condensates were investigated to determine their effect on the air-void system in fresh and hardened concrete.
