Classical dispersant usage options in cement and gypsum based systems are: 1. Reduce water-binder ratio (w/b) in order to increase strength and durability at a given workability. 2. Increase workability at a given w/b and strength. 3. Save binder at a given w/b with additional benefits, e.g. lower shrinkage, creep, hydration heat, cost reduction.
