Maximize Concrete Performance Water Retention Agent WRA S690
Suspension Stabilizer Maximize Concrete Performance With Water Retaining Admixture S690
Water retention refers to the ability of these materials to retain water within their structure, which directly affects their workability, hydration, and durability. The water retention test involves subjecting a sample of cement-based material to a specific testing procedure.
The suspension stabilizer's colloidal structure prevents the solid particles from sinking even if the external shear impact vanishes, giving the cement slurry high sedimentation stability.
Stabilizers contribute significantly to the quality of a concrete mix: They prevent concrete from sedimentation and bleeding, optimize the rheological properties and improve concrete robustness. With MasterMatrix, we offer a broad range of stabilizers for each construction project.

Water retaining agent (WRA) is a kind of functional polymer material with strong water absorption capacity. It can absorb and release water repeatedly and is often used for crop growth in water shortage areas.
Water retaining admixtures can be used to improve the stability of a concrete mix made with poor quality aggregates. By this the separation of water (bleeding) can be reduced and the durability of concrete is increased. The surface quality of architectural concrete can be improved.
