Admixtures for Concrete - Memphis
Rheology-modifying admixtures increase concrete lubricity to help stiff concrete extrude easily, and lower pump pressures in more fluid concrete applications. A workability-retaining admixture provides flexible, but predictable, degrees of slump retention without retardation. It provides consistency in air-entrainment, slump, workability and strength, and minimize the need for jobsite slump adjustment using water or high-range water-reducing admixture.
