Technical Data Sheet Declaration Of Performances Safety Data Sheet Description Chryso®WRDA 90 is a mid‑range water reducing admixture designed for use in concrete and cement‑based grouts. It can be used to reduce water content in concretes of normal workability, resulting in increased early and ultimate compressive strength, as well as improved durability. Chryso®WRDA 90 acts as a powerful deflocculating agent, dispersing cement particles to significantly improve the flow characteristics of the cement paste. It may be used as a plasticiser at low dosages or as a mid‑range water reducer at moderate dosages, without excessive retardation. The product is manufactured under controlled conditions and conforms to EN 934‑2. Application areas Chryso®WRDA 90 is suitable for: Ready‑mixed concrete General concrete construction Cement‑based grouts The product is compatible with most Portland cements and is effective in concretes containing fly ash or ground granulated blastfurnace slag (GGBS). Chryso®WRDA 90 is compatible with Chryso admixtures commonly used in concrete production. Each admixture must be added separately The presence of other chemicals may affect performance Consult Chryso Technical Services where combined admixture systems are used. Benefits Typical water reduction of around 10%, leading to improved strength and durability Facilitates reduction in cement content Predictable and controlled setting characteristics within the recommended dosage range Compatible with fly ash and GGBS concretes Extends workability retention, particularly in high ambient temperatures Improves concrete cohesion Reduces permeability by limiting capillary pore formation Packaging Container of 1000L Bulk delivery on request 15L Container
