Technical Data Sheet Declaration Of Performances Safety Data Sheet Description Quad® 420 is a new‑generation water‑reducing plasticising admixture incorporating Quad® technology. Developed using advanced hybrid polymer technology, it is designed to deliver high water reduction, extended slump retention, and homogeneous concrete performance across a wide dosage range. Quad® 420 is particularly suited to ready‑mix concrete produced with high water demand aggregates. It provides robust and consistent concrete performance while supporting strength development, pumpability, and workability retention. Application areas Types of Application Ready‑mix concrete Concrete requiring extended workability retention Concrete produced with high water demand aggregates Pumped concrete Workability classes up to F5 Compatibility with Cements All types of cement Pulverised fuel ash (PFA) Ground granulated blastfurnace slag (GGBS) Compatibility with Other Admixtures Chryso®Air range Chryso®Omega range Chryso®Optima range We recommend contacting our Technical Department for use with special cements. Benefits High water reduction Extended workability and slump retention Produces homogeneous concrete Excellent pumpability and low‑viscosity rheology Suitable for use with crushed aggregates Increases concrete strength Supports cement optimisation without strength loss Robust performance with good tolerance to water addition Wide dosage range for mix flexibility Packaging Container of 1000L 215 L Barrel Bulk delivery on request
