He adds that the improved aesthetics of the concrete was achieved by the production of homogenous concrete devoid of bleeding characteristics.
Chryso France met the product development challenges by creating an entirely new molecule. “Chryso is the only admixture producer to have evolved structures based on the chemistry of polyoxyethylene diphosphonates. “These structures improve concrete performance and maintain workability. “Further, the company is a leader in the chemistry of polyoxyethelene polycarboxylates with, for example, the recent development of its Chrysofluid Optima and Premia ranges of new-generation water-reducing admixtures. “Given the expertise in these two areas and in organo-mineral interactions, Chryso created the molecule and Chrysoplast Omega 101 emerged,” Seymore explained.
Recent tests of the new plasticiser showed that it improves concrete cohesion substantially through maximum aggregate coating, and prevents bleed-water rising to the surface. Further, European and local trials showed that workability can be maintained for two hours, using dosages ranging from 0,3% to 0,5% of cementitious content.
