Abstract
A dispersant composition for use in gypsum and/or cementitious compositions that includes, in combination, a polycarboxylate-based superplasticizer and a synergistically effective amount of an aluminum salt. The presence of the aluminum salt, such as aluminum chlorohydrate, improves the performance of the polycarboxylate-based superplasticizer.
