Hoffmann Green Cement announces the granting of the H-EVA patent in China for its activated clay-based 0% clinker cement
One year after the granting of the Chinese patent for its H-P2A binder, Hoffmann Green Cement is stepping up the development of intellectual property in this territory by obtaining a patent for its H-EVA 0% clinker cement.
After more than three years of analysis, the H-EVA patent has been validated by the Chinese Patent Office under number CN 201880079822.X.
As a reminder, H-EVA is a 0% clinker cement based on alkaline ettringitic technology using activated clay, in the form of a powder that can be stored in silos. With a mechanical strength of up to 60 megapascals at 28 days, its solid technical performance means it can be used for all types of concrete applications in buildings and on roads. H-EVA is used in particular by the Bouygues Construction group for projects using 0% clinker clay concrete.
