ABSTRACT:
Superplasticizers with improved water reducing properties for cement, cement slurries, mortar, grout and concrete are formed from synergistic mixtures of (1) aromatic sulfonic acid formaldehyde condensates, such as the sodium salt of naphthalene sulfonic acid formaldehyde condensate and (2) hydroxy aromatic compounds such as pyrogallol and gallic acid. Addition of these mixtures to the same cementitious materials also results in improved compressive strength.
