Formulated additives that modify workability, water demand and setting behavior of concrete.
Concrete admixtures are formulated products added to concrete during mixing to modify its properties — for example workability, water requirement, setting time or durability.
Admixture types and their performance differ significantly between formulations. Tell us about your concrete application, mix design and performance targets so we can confirm a suitable product and provide its technical documentation.
Typical uses for this chemical. Suitability for a specific process, and grade requirements for food, pharmaceutical or potable-water use, should be confirmed with our team.

Admixture standards define performance (water reduction, setting time, strength) rather than composition, so solids, density and pH are declared per product. Trial mixes with local cement are recommended.
