Air entrainment in the presence of superplasticizers

, 1983
Air-entrained and plain mortar specimens (cement-sand ratio = 1:3, water-cement ratio = 0.65) were prepared using a modified sulfonated polymer, a naphthalene-formaldehyde condensate, or a sulfonated melamine formaldehyde admixture at two levels of concentration.
