Technical Data Sheet Declaration Of Performances Safety Data Sheet Description Chryso®Omega 155 is a new‑generation water‑reducing plasticiser developed to optimise cement content while achieving a specified slump class. Its high flexibility allows use across a wide dosage range for numerous concrete types, including low water/cement ratio mixes or applications requiring increased workability without additional cement. Chryso®Omega 155 enables extended consistence retention and the production of high‑workability or flowing concretes without increasing mix water content. It is particularly recommended for ready‑mix concrete where transport time or warm‑weather conditions must be accommodated. Application areas Chryso®Omega 155 is suitable for: Very plastic to fluid concretes Ready‑mix concrete Warm‑weather concreting Concretes requiring increased workability without added water Chryso®Omega 155 is compatible with: All types of cement Pulverised fuel ash Ground granulated blastfurnace slag (GGBS) For use with special cements, including white cement, consultation with Chryso Technical Services is recommended. All cement types Benefits Extended consistence retention Improved compaction Increased concrete strength development Cement optimisation without loss of performance Wide range of concrete applications Flexible and versatile dosage range Packaging Container of 1000L 215 L Barrel Bulk delivery on request
