Chryso®WRDA

Concrete water reducing admixtures

Versatile Water Reducing Solutions for Improved Concrete Performance and Efficiency

The Chryso®WRDA range comprises high-performance concrete water reducing admixtures designed to improve workability, strength and overall mix efficiency. By dispersing cement particles effectively, these solutions reduce water demand while maintaining or enhancing concrete performance.

Suitable for a wide range of applications, Chryso®WRDA admixtures support flexible mix design, enabling improved early and ultimate strengths, reduced permeability and enhanced durability. The range is compatible with modern concrete requirements, including the use of supplementary cementitious materials such as fly ash and GGBS.
