It is particularly recommended for highly fluid ready‑mix concretes and applications involving transport over extended distances. Chryso®Optima 1325 offers excellent flexibility and can be used across a wide range of concrete mixes, including low water/cement ratio concretes or to increase slump class without the need for additional cement. High workability and flowing concretes can be achieved without increasing the mix water content. Application areas Chryso®Optima 1325 is suitable for: Very plastic to fluid concretes Self‑compacting concrete (SCC) Ready‑mix concrete Warm‑weather concreting Cementitious flowing screeds Chryso®Optima 1325 is compatible with: All types of cement Pulverised fuel ash (PFA) Ground granulated blastfurnace slag (GGBS) For use with special cements, including white cement, consult Chryso Technical Services.
