Technical Data Sheet Safety Data Sheet Description Chryso®Optima 1215 is a new‑generation superplasticiser based on advanced polymer technology. Thanks to its specific molecular structure, CHRYSO® Optima 1215 enables the production of cohesive, low‑viscosity concrete with long workability retention. It allows the formulation of highly workable concrete while reducing the water‑to‑cement ratio. Chryso®Optima 1215 is particularly suitable for pumped concrete over long distances. Due to its performance characteristics, CHRYSO® Optima 1215 is highly suitable for civil engineering works and the ready‑mix concrete industry. Application areas All cement types Extended workability retention Architectural concrete High Performance Concrete – Very High Performance Concrete Ready-mix concrete
