Abstract
Additives for cementitious materials are formed from mixtures of (1) salts of naphthalene or lower alkyl substituted naphthalene sulfonic acid formaldehyde condensates and (2) water-soluble resins selected from the group consisting of resorcinol- formaldehyde and catechol-formaldehyde resins. Addition of these mixtures to cementitious materials results in improved slump and compressive strength.
