Abstract:
A superplasticizing admixture of the sulphonated melamine formaldehyde condensate type was tested in the laboratory for its effect on concrete mixes with a nominal slump of 3 in. (75 mm) and 415 kg/m3, respectively). A total of nine mixes were prepared. All mixes contained an air entraining admixture.
