Additives for cementitious compositions
Additives for cementitious compositions which are mixtures of (1) salts such as the sodium salt of a condensation product of naphthalenesulfonic acid and formaldehyde and (2) zinc salts increase compressive strengths and reduce water contents of hardened cementitious compositions. Useful additives i...

| description | Additives for cementitious compositions which are mixtures of (1) salts such as the sodium salt of a condensation product of naphthalenesulfonic acid and formaldehyde and (2) zinc salts increase compressive strengths and reduce water contents of hardened cementitious compositions. Useful additives include mixtures of from 65% to about 75% by weight of a sodium salt of a condensation product of naphthalenesulfonic acid and formaldehyde and from about 25 to about 35% by weight of a zinc salt such as zinc sulfate, zinc chloride, zinc acetate or the like. Effective amounts of these additives are added to cementitious compositions to improve their properties. Addition of effective amounts of these mixtures in cementitious strengths from 25 to 30% greater over those obtained with a sodium salt of the condensation product. |
