Technical Data Sheet Declaration Of Performances Safety Data Sheet Description Chryso®WRDA P4 is a liquid water‑reducing plasticising admixture developed for use across a wide range of concrete applications under all seasonal conditions. It acts by adsorption on cement particles, producing a powerful deflocculating effect that improves concrete performance. Through effective water reduction, Chryso®WRDA P4 can be used to increase compressive strength or to reduce cement content, improving mix economics. It also contributes to reduced concrete permeability. The product is formulated under controlled conditions to ensure consistent quality and conforms to EN 934‑2. Application areas Chryso®WRDA P4 is suitable for: Ready‑mixed concrete General construction concrete Concreting operations in high ambient temperatures Applications requiring improved workability and durability The product is compatible with most Portland cements and is effective in concretes containing fly ash or ground granulated blastfurnace slag (GGBS). Chryso®WRDA P4 is compatible with admixtures commonly used in concrete production. Each admixture must be added separately The presence of other chemical admixtures may affect performance Consult Chryso Technical Services where combined admixture systems are used. Benefits Typical water reduction of approximately 10% Increased compressive strength, impermeability, and durability Enables cement content reduction Excellent consistence retention Effective and predictable water‑reducing performance Limited and controlled retardation characteristics within the dosage range Compatible with fly ash and GGBS concretes Particularly beneficial in hot‑weather concreting Improves cohesion of concrete Packaging Container of 1000L Drum 205L Bulk delivery on request 15L Container
